What Happens When You Take a Step? The Walking Gait Cycle Explained

You take thousands of steps a day and you don’t even think about it. But each step follows the same pattern: two phases and five key movements that move pressure through your foot in an S-shaped curve, from your heel to your big toe. Once you understand what your foot does with each step, it’s easier to choose comfortable shoes that work for your body, not against it. What Is the Walking Gait Cycle? Dr. Matt Driscoll, DC, of Driscoll Chiropractic explains that walking is made up of two phases: the stance phase and the swing phase. It begins when one heel contacts the ground. “As your body moves forward, weight is transferred from the heel to the midfoot, followed by a push-off through the forefoot and toes.” The leg then lifts off the ground, bends at the knee, and swings forward in preparation for the next step.  Walkers may typically be in stance phase 60 percent of the time and swing phase 40 percent of the time, moving from step to step. This can vary based on your step length and stride duration. Both feet are on the ground twice per cycle, once just after your heel lands and once just before you push off. Each lasts about 10% of the cycle. In walking, at least one foot is always down. The 5 Key Movements of Walking Before you take a step, your foot has three main points of contact with the ground: the heel, the base of the big toe, and the base of the little toe. Driscoll says, “These three points help create a stable foundation for movement.” Once you start walking, your gait is not a straight heel-to-toe motion. Each step propels you forward. “This continuous cycle allows for smooth, efficient movement and helps us walk with balance and stability,” Dr. Driscoll says. Stance phase – your foot is in contact with the ground Heel strike Your foot meets the ground and impact is absorbed into your heel. Load and brake Your heel brakes forward motion and absorbs the load as your weight shifts 
into the midfoot. Stabilize Your body stabilizes and the foot rolls forward from the midfoot to the ball of your foot. Push-off The heel lifts and power shifts to your big toe to push off and propel your
body forward. Swing phase: Swing Your foot leaves the ground and swings forward as the other foot prepares to strike and restart the cycle. Is It Normal to Land on Your Heel When You Walk? Dr. Ray McClanahan, DPM, podiatrist at NW Foot & Ankle and inventor of Correct Toes, says that gait depends on many variables so there’s no universal standard. “It is normal for most people to first land on their heels while walking.” Where your foot lands matters more than which part lands first. Landing on your heel under your body is different from landing on your heel with your foot reaching out in front of you.  Landing under your body usually feels smoother, especially in barefoot shoes, where you can feel the ground. Learn how to land under your body and walk with your glutes in our guide to walking barefoot. How Does Pressure Move Through Your Foot? (The S-Curve) Your browser does not support video playback. In the animation above, you can see how pressure moves from your heel, along the outside of your foot, and across to your big toe with each step. Because walkers land heel first, the heel takes the first impact with every step.  If you follow the pressure path of a walking step, you’ll see it travel along the outside of your foot, then sweep across to your big toe, where you push off. Your heel absorbs the most force at the start of the step, while your big toe uses the most power at push-off. Your inner arch and outer toes act more as stabilizers when most of your foot is in the ground during the weight change from heel to toe. How Do Shoes Affect Your Walking Gait? Dr. Alissa Kuizinas, DPM, a podiatrist at Wellness in Motion says cushioning, stability features and heel-to-toe drop all affect how much pressure lands on your joints and how hard your muscles work with each step. Stiffer, more structured shoes do some of that work for you.  On the other hand, she says “barefoot shoes will require you to use your full range of motion of the joints in your lower body. This can be great, but it can also expose compensation patterns.” One of the key differentiators in barefoot shoes is the minimal cushioning provides immediate ground feedback. Walking is a great place to start with barefoot shoes, since it’s lower impact.” As Dr. Driscoll says, “Footwear that respects the natural design of the foot can help improve movement efficiency, comfort, strength, and long-term foot health.”  An Outsole Built on the Same Curve: Pacer Lite The Pacer Lite is Xero Shoes’ first performance walking shoe and it was designed with the walking gait in mind. It is still a true barefoot shoe: zero drop, foot-shaped toe box, and 13.5mm stack (a 10mm sole plus a 3.5mm removable insole), but with special features built for how you actually walk. When it comes to designing a barefoot walking shoe, Xero Shoes’ product designers studied the walking gait and the way pressure moves through the foot with each stride.  “In walking, the pressure goes into the heel first, then disperses along the S-curve,” says product designer Ciera Schelling. “The design revolved around understanding where that first pressure is, how it moves through the foot, and where you need traction because of it.” The outsole was the most important aspect of the Pacer Lite. They considered traction and durability in the higher pressure areas of the outsole, like the heel and forefoot. “We started with our signature chevrons, softened them, and warped them to follow the S-curve,” Ciera says. “You can actually see a line in the outsole that follows that S-curve, so as your foot bends, the shoe bends with it.” The heel-strike support is also a first for Xero. This embedded performance foam sits exactly where your heel strikes the ground, absorbing that impact without dulling the ground feel that makes the natural walking gait so efficient. The table below shares more about how the Pacer Lite works with your walking gait.  Movement Outsole zone Why it’s there Heel strike Heel-strike support  A small foam insert designed to soften heel-strike Load and brake Braking traction Grip while your foot absorbs the landing Stabilize Stability zone Support and smaller lugs where pressure is lighter Push-off Forward motion Traction where your big toe levers you forward Swing Light weight Cutouts keep the shoe light step after step FAQs What is the walking gait cycle? Every step has two phases and five movements. A full gait cycle is measured by a full cycle of one foot, from hitting the ground to the next time that same foot hits the ground. Is it normal to land on my heel when I walk?  Yes. At an everyday walking pace, most people land heel first, according to Dr. McClanahan. How is walking gait different from running gait? Dr. Kuizinas explains that walking and running are two distinct patterns of gait. “Walking is essentially a continuous transfer of weight from one leg to the other, where one foot is always on the ground with a period of time where both feet are on the ground at the same time.” The difference with running, she says, is only one foot is on the ground at a time, and there is a brief time where both feet are off the ground, requiring more muscle elasticity and shock absorption. Walking depends on controlled weight transfer and stability, while running relies more on muscle elasticity and absorbing shock. Does what I wear change how I walk?  Yes. Dr. Kuizinas says cushioning, stability features and heel-to-toe drop all change how your foot and joints work with each step. Barefoot shoes let your foot use its full range of motion. Learn more about picking walking shoes.  What is good walking posture?  Walking should feel natural, and everyone's gait will look slightly different. As Dr. Driscoll says, “the upper body should remain relaxed and loose, while most of the movement and force generation occurs from the hips down.” There are a few reminders that will help you as you’re learning to walk barefoot or in barefoot shoes.  The content of this post is for educational and informational purposes only and does not constitute and is not intended to be a substitute for professional medical advice, diagnosis or treatment.

What to Look for in Barefoot Walking Shoes

What to Look for in Barefoot Walking Shoes

Say you’ve heard all the benefits of walking in barefoot shoes and you’re ready to make the jump. Make sure you know what to look for when shopping. The best barefoot shoes for walking have a wide, foot-shaped toe box, a thin and flexible sole, and a zero-drop design that keeps your heel and forefoot level. Just as important is fit: your toes should have room to spread while your heel and midfoot stay secure. There is so much guidance on finding the right running shoes, but walking has different needs. For one, most people land heel first when they walk, and some days you might be climbing hills or carrying a weighted vest. Here’s what to look for, with advice from a podiatrist, a chiropractor and the designer behind our new walking shoe. Are Barefoot Shoes Good for Walking? “Barefoot shoes can be great for walking,” says Dr. Alissa Kuizinas, DPM of Wellness in Motion. “They allow the foot to utilize the full range of motion of the joints, and to use all of the lower extremity muscles fluidly. They also allow great feedback from the ground.” However, barefoot shoes may not be an instant fit for everyone. Dr. Kuizinas notes that people with limited joint mobility, current injuries or significant stiffness may need more time, and that soft surfaces are easier to start on than pavement. Barefoot vs. Zero Drop Shoes Going completely barefoot isn't for everyone and isn't right for every occasion.  The good news is that you can walk in barefoot (or minimalist) shoes instead. That's why we created Xero Shoes - so you feel the benefits of being barefoot while still protecting your feet.  Barefoot shoes are designed to feel like you’re barefoot with a foot-shaped design and minimal cushioning, but you get a balance of ground-feel and much-needed protection. People often use barefoot and zero-drop shoes interchangeably, which isn’t accurate, since you can have a zero-drop shoe with a stiff, or highly cushioned sole. Zero-drop shoes are characterized as flat from heel to toe.  When it comes to walking, Dr. Matt Driscoll, DC of Driscoll Chiropractic, says that a zero-drop design creates a more balanced relationship between the muscles on the front of the lower leg (the shin muscles) and those on the back (the calves). “This allows muscles to regain their optimal length and strength, improving their ability to absorb force efficiently and enhance movement.” The Barefoot Shoe Checklist  The characteristics of a truly “barefoot shoe” are: Foot-shaped toe box Zero-drop, flat from heel to toe Flexible sole that bends and flexes with your feet Thin sole with minimal cushioning for ground feel No arch support Lightweight Two Tests You Can Do at Home Toe Box Test: Take out the insole and stand on it. If your foot spills past the edges, the shoe is too narrow. Dr. Kuizinas says “your toes should sit comfortably without scrunching.” Flex Test: Bend the shoe toe to heel, then twist it. It should move easily in your hands. Xero Shoes checks all the “barefoot boxes.” But it’s not just about the design, it’s how you wear the shoes. Once you decide how you’ll wear barefoot shoes, like for workouts, hiking or casual wear, you’ll find more activity-specific features.  What to Look for in Barefoot Walking Shoes There are a few specifics that you’ll want to look for as you pick out barefoot walking shoes.  Dr. Kuizinas says the features that matter most for walking shoes are the fit, cushion level, and structure of the shoe. Walkers want to find the shoe that matches their specific foot needs. Fit When you’re walking, having room for the toes to spread out helps power the push off as you move through your stride. Having wide shoes or wide feet is different than a wide toe box. It’s important that the design is foot-shaped where the toe box is wide but the heel and midfoot are held securely in place, instead of wide throughout the entire shoe.  Width isn’t the only thing that matters, consider depth too: if you have larger toes or toes that curl, you may need a taller toe box Sole Thickness “Ideal thickness of the sole really depends on the person,” says Dr. Kuizinas. “For some people a thinner sole is great because it allows for excellent ground feel and feedback and improves stability and balance. For others, thicker soles can be helpful to attenuate shock.” That’s the thinking behind the Pacer Lite: it’s a walking shoe that still has a thin, flexible 13.5mm sole for ground feel, but added protection with a heel crash pad right where walkers land. Flexibility Your feet are meant to bend and flex naturally throughout your walking gait, so that’s why sole flexibility is so important for everyday walking. Walking shoes with a flexible sole that can bend easily promotes natural movement through the foot's range of motion.  Upper and Breathability If you’re logging your 10,000 steps, you may spend longer in walking shoes than in a pair you wear for a quick run. You’ll want a shoe with a breathable upper to keep feet cool on long miles. The Pacer Lite’s flexible upper features breathable engineered mesh. Traction Look for tread where your foot actually meets the ground: under the heel, where you land, and under the ball of the foot and big toe, where you push off. The more varied your walks (pavement, park paths, hills), the more traction matters. Does a Walking Shoe Need Anything Different? Yes. Walking loads your foot differently than running. You land heel first more often, and one foot is always on the ground. “Barefoot shoes will require you to use your full range of motion of the joints in your lower body,” Dr. Kuizinas says. “Features such as cushioning level, added stability components, and heel-toe drop will affect peak pressures on joints and how much muscle force is required with each step.” When you look into the technical design of creating a barefoot walking shoe, there is much more that goes into it than you think.  The design team mapped four ways people use walking shoes, from most to least common: walking, fast walking, hilling (walking uphill), and rucking (walking with a weighted vest or pack).  Walking uphill shifts weight to the ball of your foot and toes, so a flexible forefoot allows for natural motion. You also need traction under the forefoot so you don’t slip. Rucking adds weight to every step, putting more pressure on your heel and the ball of your foot. That’s where an outsole needs extra durability. Sizing You may have learned that you need a certain amount of space between your toes and the front of your shoes. That’s because most shoes taper inward and squeeze your toes, so you’re adding a thumb’s width or more to make your toes feel more comfortable. With barefoot shoes, you may not have to size up, especially if you have a narrower foot. Your toes will still have room to spread, but your shoes will feel secure as you’re walking. Learn more about sizing your Xero Shoes.  When shopping for barefoot walking shoes, prioritize a foot-shaped toe box, a thin and flexible sole, and a zero-drop design. Then look for features made for how you walk. That’s exactly what we built the Pacer Lite to do.  How you walk changes how your foot meets the ground. Our product team designed the Pacer Lite’s outsole to follow the natural S-curve of your walking gait. "When you walk, pressure spikes as your heel hits the ground, transitions through the arch, and then spikes again as you push off your toes. Those are the two most important moments, so that's where we focused," says Ciera Schelling, one of Xero Shoes’ Product Designers. To absorb the impact during each foot strike, an embedded performance foam sits exactly where your heel strikes the ground, absorbing that impact without dulling the ground feel that makes the natural walking gait so efficient. This foam is just in the heel, so you still get the full flexibility and range of motion in the rest of your feet.  The outsole’s design also prioritizes traction and durability depending on how you walk. Bigger, tougher lugs were placed at the heel and forefoot where the pressure is. These lugs wear down faster.  The arch and outer toes carry less pressure and mainly help stabilize your foot, so those lugs are smaller. That also saves weight. FAQs How much room should a barefoot shoe’s toe box have? Dr. Kuizinas says to look for a wider, foot-shaped toe box that allows your toes to spread. You may also want to look for a taller toe box depth, particularly if you feel you need more room above your toes. How thick should a walking shoe’s sole be? A thinner sole gives you better ground feel and feedback. But Dr. Kuizinas notes that for some people, “thicker soles can be helpful to attenuate shock and reduce overall loading of the feet with each step.” It depends on your foot strength, flexibility and how used to barefoot shoes you are. Can you wear other barefoot shoes for walking? Yes, most barefoot shoes have the same features like a wide toe box, zero-drop flexible sole, and minimal cushioning, you’ll get ground feedback and natural comfort. The Pacer Lite barefoot walking shoe, has a walk-specific outsole that was designed for the walking gait, featuring a small layer of foam in the heel to absorb the impact from heel striking, which is common in walking.   Are barefoot shoes good for rucking or walking with a weighted vest?  Since rucking adds more load to your steps, barefoot shoes can be a good step up once your feet are adjusted. Adding weight increases the load on your feet, so build up to it gradually. The Pacer Lite’s outsole was designed with rucking in mind, with larger lugs at the heel and ball of the foot, where weighted walking puts the most pressure. As Dr. Driscoll says, the key is to transition gradually, listen to your body, and allow sufficient time for adaptation. More info on transitioning to barefoot shoes.

Max-Cushion vs. Barefoot Shoes: It’s not All or Nothing

Max-Cushion vs. Barefoot Shoes: It’s not All or Nothing

Look around the gym, the jogging paths, or the coffee line, and you'll notice a lot of shoe between most people’s feet and the ground. Max-cushion shoes, with their thick stacks of soft foam, are everywhere. A recent Wall Street Journal article interviewed podiatrists, sports-medicine doctors, and coaches about how cushioning changes the way we move.  So is more cushion bad? Not exactly. Cushioning is a trade-off: it can feel great, but it changes how much your feet feel and do with every step. Their advice wasn’t to go all-in on cushioning or minimal. It was to mix up your footwear, rotating between shoes with different cushioning and stack heights.  What are max-cushion shoes? Max-cushion shoes have a thick layer of foam between your foot and the ground. According to the WSJ article, some carry close to two inches of it.  This could add stack height and heel-to-toe drop. Stack height is the thickness of the sole and how far your foot sits above the ground. Heel-to-toe drop is how much higher your heel sits than your toes.  Xero Shoes and true barefoot shoes are always zero-drop, so the heel to toe are the same level, and typically close to the ground. Today it's hard to find a running or walking shoe that isn't sitting on a platform of foam. We think there’s a good case for adding barefoot shoes to your shoe closet. What changes with more cushioning? Thick foam changes two things: how much information your feet get from the ground, and how much they have to work to keep you steady. Ground feel. Your feet have thousands of nerve endings that provide feedback to the rest of your body.  Dr. Ray McClanahan, DPM, podiatrist at NW Foot & Ankle and inventor of Correct Toes says that feedback plays a big role in how well we move. “Thick shoes can blunt sensory information and hamper human movement.” Stability. Think about standing on a pillow. Your foot sinks into the soft surface and has to work harder to balance. Stack another pillow and it may be even harder to balance. You may notice your feet wobble side to side and your ankles and knees may quiver.  Now just stand barefoot on the ground. Notice how the direct contact to the ground feels. You may see your toes spread out. Do you feel more stable? Curious how footwear plays into balance? Here's what one study found about minimal shoes and balance. Impact. You might expect more foam to soften every landing, but a 2018 study in Scientific Reports found the opposite. Researchers had 12 runners try both a max-cushion shoe and a conventional running shoe. In the max-cushion pair, their legs stiffened more on landing and the initial impact force was higher, especially at faster speeds. The researchers think the body may brace against soft foam, much the way it does when running on a softer surface. The study was small and looked at running, not walking, but it's a good reminder that more cushion may not soften the impact. Learn more about just what happens when you take a step. Thin, flexible soles are core to every Xero Shoes design: they protect your feet while letting you feel the ground. What can the barefoot running boom teach us? In the late 2000s, the bestselling book Born to Run sparked a barefoot running craze. Lots of people traded their cushioned shoes for barefoot shoes overnight. That led to some backlash, because many people's feet never got the chance to adjust. It was too much change, too fast. Dr. McClanahan has worked with athletes for 31 years. He recommends controlled barefoot training to the athletes he treats. His advice for everyone else: "Our feet and bodies are capable of so much more than most people realize. If you want to learn what you are really capable of, pay careful attention to what you put on your feet, and your body will thank you for years to come." Xero Shoes' advice: go slow and let your feet adapt as you transition to barefoot shoes. How to add barefoot shoes to your rotation You don't have to throw out all your cushioned shoes. If anything, the experts interviewed in WSJ recommend rotating shoes with different amounts of cushioning and stack height, and introducing any new style very gradually. We like to call it microdosing. Here's a simple way to start: Week 1: Wear barefoot shoes for 2-3 short walks or errands. Week 2: Add 5 minutes to your walks or an extra errand. Weeks 3 and 4: Wear them every other day and go a little longer each time. After that: Work them into everyday wear. If you’re eager to run in barefoot shoes, it’s best to ease gradually. Dr. McClanahan says that people who suddenly switch to barefoot style shoes when they haven't properly trained their bodies to do so safely is what tends to get people in trouble. He recommends a slow progressive transition. “... for those new to barefoot shoes, it can take months to years to accomplish without injury.” Listen to your feet as you go. Tight calves or tired feet are common as they adapt, so slow down if you need to.  FAQ What is stack height in shoes? Stack height is the thickness of a shoe's sole, or how far your foot sits above the ground. Max-cushion shoes have a high stack height. Barefoot-inspired shoes have a low one, often just a few millimeters, so you can feel the ground beneath you. Are zero-drop shoes the same as barefoot shoes? Not always. Zero-drop means your heel and toes sit at the same height. A shoe can be zero-drop and still heavily cushioned. Barefoot-inspired shoes are zero-drop and also have a thin, flexible sole and a wide toe box that lets your toes spread. Can I wear barefoot shoes and cushioned shoes in the same week? Yes, and it's a great way to start. Rotating between different types of shoes gives your feet a variety of experiences. Start with short sessions in barefoot-inspired shoes, like a walk or an errand, and add more time as your feet adapt. How long does it take to get used to barefoot shoes? It varies from person to person. Some people feel at home within a few weeks of everyday walking, while others take several months, especially before running. Start small, pay attention to how your calves and feet feel, and increase your time gradually. Learn more about transitioning to barefoot shoes. The bottom line: rotate your shoes You don’t have to make the choice for max cushion or barefoot. Different shoes change how your feet feel and move. Many experts agree: different shoes introduced slowly, beats an overnight switch in either direction.

Barefoot Sandals for slacklining

Barefoot Sandals are for more than running

The two most popular comments I hear from people seeing Xero Shoes barefoot sandals for the first time are:"You can't really run in those, can you?"and"I'm not a runner so I can't use those."Make up your mind people! ;-)So, some people equate barefoot-inspired sandals with running, and others can't fathom doing an ultramarathon without giant maximalist shoes with tons of padding and "motion control."It's true that Xero Shoes were inspired by the huaraches sandals worn by the Tarahumara of Mexico, who make their sandals from scraps of tire and leather laces (they're stiff and heavy, btw). And the Tarahumara are known for running long distances in their sandals. And it's true that the early adopters of Xero Shoes were barefoot runners. And it's true that we've had hundreds, if not thousands, of emails from customers all around the world who've run everything from 5k - 100 mile races in Xeros.But that doesn't mean you have to run in them. Lena, my wife, co-founder of Xero Shoes, and our COO... she's a hiker, not a runner. But she mostly wears her Xero Shoes as her daily footwear.I'm a competitive sprinter, and wear my sandals for daily wear -- I haven't had a "normal" pair of shoes on my feet for 5 years -- and for all my drills and warm-ups on the track (for sprinting, I'm in a pair of spikes, which you need for traction and maximum speed).I like to ask people, "Do you enjoy being barefoot?" And if they say Yes, I say, "Well these sandals give you the closest thing to that fun, free barefoot feeling, but with a layer of protection."And with that combo, our customers have done practically everything you can think of in Xero Shoes -- walking, hiking, sky diving, paddle boarding, biking, kayaking, hanging out on the beach, a night on the town, even 100k ultramarathons through the jungles of Costa Rica.Here's a pic of Michelle, an awesome YogaSlacker (that's people who can do yoga poses on a slack line), showing what she can do in Xeros!Put on your Xero Shoes and go everywhere, do everything... naturally!

Man running on hamster wheel

Is running in our DNA?

One reason scientists study mice is, much as we may not want to admit it, we have a lot in common with our rodent relatives.We share enough DNA and physiology that studying mice often reveals quite a bit about us humans.So, does this recent study from Leiden University explain why many of us like to run?In short, neurophysiologist Johanna Meijer set up a running wheel -- yes, the kind you would put in a mouse, or rat, or hamster cage -- in her backyard and, after enticing animals to come near with the help of some food, watched that they ran on the wheel. Not to get the food. Just to run.Wild mice would often come back and run as much as caged mice -- mice who usually have nothing else to do -- would.As Emily Underwood says of the study,Rats, shrews, and even frogs found their way to the wheel—more than 200,000 animals over 3 years. The creatures seemed to relish the feeling of running without going anywhere.Maybe this tells us why we like to run.Or maybe it just explains treadmill sales ;-)

Daniel Lieberman studies the Tarahumara running

Daniel Lieberman studies the Tarahumara running

Dr. Daniel Lieberman is one of the fathers of the barefoot running movement. His study showing how barefoot runners strike the ground with less force than shod runners, combined with Christopher McDougall's book, Born to Run, catalyzed the growth of barefoot and minimalist running. Well, it's as if Dr. Lieberman had a child with BTR, since his new study looks at how the Tarahumara run. And, more, it compares Tarahumara runners in huaraches to younger Tarahumara who run in padded running shoes. You can read the study for free here. Before I talk about what the study reveals (and what it doesn't), let me address a myth about barefoot running...Barefoot Running Myth #1One of the myths of barefoot running is that there is ONE WAY to do it: Your foot hits the ground in a certain way, you move your legs at a specific speed, you hold your arms in one configuration, and you run long, long distances. Hogwash, I say (as if I lived in the 30's). There's actually quite a bit of individual difference among competent barefoot runners, even though a few concepts are consistent. The problem with this myth is that it interferes with one of our brain's favorite hobbies, namely:The Brain's Favorite HobbyBrains like to know how things work. They like patterns. They like consistency. Oh, they're fascinated by the novel and new, but when it comes to survival, they like to know the rules. See the problem? When we want to learn something new, like how to run barefoot, we want to know "What's the one way I should do this? Show me a video I can imitate. Give me the rules." But, as I just said, there's not ONE way, there are variations of a theme.We now return to our regularly scheduled programAnd this brings us back to Lieberman's study. He finds some real variation in foot strike patterns among the huarache-wearing Tarahumara.40% primarily using midfoot strikes, 30% primarily using forefoot strikes, and 30% primarily using rearfoot strikes.70% land in a way that's consistent with the bigger picture of barefoot running, namely, don't land on your heels. But 30% DO heel strike! "How could they possibly rearfoot (or heel) strike?" you may ask. There are a couple of answers/comments: Footstrike isn't everything. Just because their heel touches the ground first, that doesn't mean they're putting extra force into their bodies by doing so. Which part of your foot touches the ground first doesn't always tell you everything you need to know. It's possible to have your heel contact the ground first but, because of your speed and where you place your foot in relationship to your center of mass, not apply force into the ground until your midfoot hits. So you could look like a heel striker, but apply force like a midfoot striker. Traditional huaraches are thick and stiff. If you haven't held a pair of huaraches made from tires and leather, you'll be in for a shock when you do. They're heavy and stiff. They reduce the amount of feedback you get from the ground... on purpose. Some of those Copper Canyon trails are seriously pointy, pokey, sticky. So it may be  that some Tarahumara heel strike because they don't get the same feedback -- pain -- that one would get running barefoot. Traditional Tarahumara Huarache -- thick and stiff So don't get hung up on the fact that 30% of the Tarahumara that Lieberman studied heel strike. But also don't think, "Well, if they can do it, so can I!" More about that later. Next, Lieberman pointed out:In contrast, 75% of the conventionally shod Tarahumara primarily used rearfoot strikes, and 25% primarily used midfoot strikes.That's an interesting one:  change the shoes, change the gait. I saw that when I was in Dr. Bill Sands' lab. Dr. Sands is the former head of biomechanics and engineering for the US Olympic Committee. He had hundreds of videos showing how the same runner will change their footstrike and, ofter, their entire gait, depending on the shoe they wear. That shod runners more often land on their heels isn't surprising to people familiar with barefoot running since we make the opposite argument: take OFF your shoes and your gait will change (over time and with some attention).What Lieberman's Study Does NOT SayLieberman looked at a number of other aspects of the gait of huarache-wearing and shoe-wearing Tarahumara: overstriding (the huarache wearers were less likely to do so), flexion of the joints (huarache wearers bend their joints -- use their springs -- more), and arch stiffness (huarache-wearers have stronger arches). Read the study to find out more. But what he does not say is just as important as what he does. He doesn't say "switch to sandals," or "midfoot or forefoot strike is better" or anything prescriptive. Lieberman is being especially circumspect about the meaning of the data he collected. This is, perhaps, a good thing, given how evangelical barefoot runners often take any seemingly pro-barefoot news as an excuse to have a shoe-burning party, which then backfires when any seemingly anti-barefoot news causes shod runners to chime in with "Nah-nee nah-nee, boo-boo" (or something equally insightful).Show me the moneyNote that I say "seemingly" for both pro- and con- news. That's because there still aren't any good studies that clearly demonstrate "Barefoot is better" or "barefoot is worse." And there are no studies showing "shoes are better" either, even though there has been 45+ years to whip one of those up, and many research labs are sponsored by big shoe companies. Those of us who've been living a barefoot or truly minimalist lifestyle now have lots of personal experience about the changes that can happen. And studies like Lieberman's hopefully provide more incentive for researchers find the cash to find out if we're unusual or if anyone who ditches their shoes can have the same kinds of expeiences (okay we know the answer to THAT, but you know what I mean ;-) ).The content of this post does not constitute and is not intended to be a substitute for professional medical advice, diagnosis or treatment.

Will Vibram Fivefingers make your feet stronger?

Will Vibram Fivefingers make your feet stronger?

Big news today in the barefoot world: Vibram settled a class action lawsuit that claimed the company deceived customers when it claimed that VFFs would decrease foot injuries and strengthen foot muscles.As reported in the Washington Post:The company agreed to put aside $3.75 million to pay refunds of as much as $94 to anyone who had bought a pair since March 21, 2009, according to Runner’s World.(Okay that was according to Runner's World as reported by the Washington Post. The Post article was the one that showed up in my newsfeed.)Further:Vibram has agreed to discontinue to make any claims that FiveFingers footwear is effective in strengthening muscles or reducing injury in its marketing and advertising campaigns, unless the company discovers new scientific evidence that proves it.This suit, and Vibram's response bring up some interesting questions.Is settling in any way an expression of guilt? Not according to Vibram:Vibram expressly denied and continues to deny any wrongdoing alleged in the Actions, and neither admits nor concedes any actual or potential fault, wrongdoing or liability,” read the court brief.While it's true that settling a lawsuit does not equate to guilt, it's kinda hard to argue that Vibram made the claims and, in fact, didn't have scientific evidence to back them up.This is similar to when Reebok and Skechers paid up after claiming their "toning shoes" would help you lose weight and firm up your butt. Those companies had to pay 25-40 million to settle their suits.Is the settlement appropriate?Let's be honest, $3.75 million is barely a slap on the wrist for a company that sold hundreds of millions of dollars worth of shoes. In fact, this is barely a tap on the arm hair on the back of the wrist.Agreeing to pay less than $4 million is clearly a payment just to make the case go away. Had they moved forward, the case could have cost tens of millions of dollars; so settling is usually a matter of cost-benefit analysis.What about the claims? Are they true?Well, here's where it gets interesting. Many people online, including on our Facebook page are, I think, confusing the issue.The question isn't whether being barefoot or, in this case, somewhat minimalist, can be helpful. Or whether you can strengthen your feet and reduce injuries by ditching your shoes.That's been my experience, and we've received hundreds of emails from Xero Shoes customers who report the same.But that's not the point.The point is: there's currently no scientific evidence to back up the claim. And if you can't prove it, you can't claim it in your advertising. That's the law. Making unsubstantiated claims can lead to "unfair enrichment."Is it fair?Ah, another interesting point. Shoe manufacturers have been making similar unsubstantiated claims for decades (more than Reebok and Skechers, mentioned above). But they haven't been taken to task for it.In my opinion, the only reason they haven't had to pay the piper is that there were never enough people who got all in a tizzy about their claims. People, by and large, just write off shoe company claims that their shoes will make you bigger, stronger, faster, as hyperbole.There was never enough mass, concentrated, public outrage to inspire someone to take action, like filing a class action lawsuit.I think the sudden and meteoric rise in interest in barefoot running, combined with claims like Vibram made, created a "perfect storm" for this kind of situation.Frankly, I'm surprised nobody has followed this with suits against other companies who've acted the same way.FWIW, Lena and I have been as diligent as possible about not making health claims, despite our experience and that of our customers, just because we knew the law. In fact, the FTC has gotten more stringent in the last few years, where companies have to be careful about even letting customers report their own experiences, since those can, arguably, be interpreted as a way of making unsubstantiated medical claims.Is this just another "McDonald's coffee" case?I've read this a lot.People comparing this suit to the one where Stella Liebeck sued McDonalds after getting burned by spilling hot coffee on herself.They say things like, "Hey, just because you went out too fast, too soon, don't go suing Vibram for your stupidity."First of all this isn't the same because the suit is a class action suit. Rarely do those result in windfall payments to the plantiffs.Secondly, it shows a misunderstanding, a common one, about Stella's suit. While people think Stella was just suing to make up for her stupidity, that's far from the case. The real issue behind that suit was that McDonalds had admitted to numerous instances of heating their coffee too much, resulting in injuries to other people, and despite that, hadn't taken any action to address the situation. More, people think Stella sued for and received WAY more money than she did. She just wanted her medical bills covered.The point being, even if Valerie Bezdeck, who brought the suit against Vibram, sustained injuries after wearing her VFFs, that's not the issue. The issue is: Can a company make unsubstantiated claims about a product? And while the answer is, "No," Vibram didn't have a day in court to argue this point.If they had, though, it might have been tricky since perhaps the most well-known study seemed to show that VFF wearers are more likely to get injured than regularly shod runners.I've previously commented on that study, BTW, and said that the real issue was the transition plan recommended by Vibram and followed by the runners in the study, compounded by the fact that the VFFs have enough padding that they decrease the sensations necessary to naturally change your gait (because you can't feel what hurts until it's too late).Is this the end of barefoot?This is the part that still irks me.Any time there's ANY news that suggests being barefoot and barefoot running will not improve your life, end world hunger, and land a man on Mars, it's written as if it's an episode of To Catch a Predator.Granted, the Washington Post article doesn't do this and, in fact, presents the reality of barefoot running perfectly:Does Vibram being caught flat-footed mean there’s no merit to barefoot running? Absolutely not. There is conflicting research on the subject, but I’ve met dozens of people who gave up the sport because of leg injuries suffered in traditional running shoes, only to have their exercise regimens revived by the minimalist variety. In fact, I’m married to one. There’s a niche for flatter-soled running gear, just as there’s a market for people who prefer to drive Maseratis instead of Mazdas.I would, of course, say barefoot is the Maserati in this analogy and that even though minimalism is currently a niche, it should be much more.But I also agree that the research needed for us to be able to make the kinds of claims that many of us have experienced isn't there yet. And, so, caution is necessary for those of us in the commercial space. And I am not claiming that your flat feet will develop arches the way mine did once I started going barefoot and in Xero Shoes.;-)What do you think?The content of this post does not constitute and is not intended to be a substitute for professional medical advice, diagnosis or treatment.

Happy Born to Run release day!

Happy Born to Run release day!

May 5th is an important day in the barefoot running world. And, for the same reason, it's one of the most important days in the Xero Shoes world.What makes it so important?As Brian Metzler from Competitor.com reminded me, "Journalist Christopher McDougall’s best-selling book “Born to Run: A Hidden Tribe, Superathletes, and the Greatest Race the World Has Never Seen” hit bookstore shelves five years ago Monday—on May 5, 2009."Brian describes 11 ways that Born To Run influenced the running world, from simply being a really great read, to inspiring the growth of ultrarunning, to creating a number of great races, to inspiring people to run barefoot, to encouraging shoe companies to make minimalist footwear (of course, if you've read anything I've written, you know I think most "minimalist shoes" are as close to barefoot as a pair of stilts).The 12th way that Chris's book influenced the world is that it was one of the inspirations for Xero Shoes.If you've read Lena's and my story, you'll know how BTR inspired us. But, more, the success of the book created a wave that we surfed. Were it not for the millions of people who read BTR, Xero Shoes would have remained a goofy little hobby.Now, on days when we work 12+ hours, I sometimes long for those hobby times ;-) ... but given the thousands of people we've been able to help -- people who can now run or walk or hike enjoyably and pain-free -- and the fun we have when a new person discovers the fun of being able to feel the world when they're out and about, we couldn't be more thankful for this anniversary.Congrats again to Chris for his success. Thanks again to him for all he's done for ALL of us. And stay tuned and cross your fingers for the Born To Run movie!

Is your body optimized for running?

Is your body optimized for running?

Harvard's Daniel Lieberman is one of the two or three people most responsible for the barefoot running boom (Christopher McDougall, who wrote Born to Run, is another... you can vote for who the third should be).Daniel is an anthropologist and has some fascinating ideas about why the way humans run (and sweat) gave us such an evolutionary advantage.In this video he talks about some of aspects of human anatomy that suggest we were "made to run."I don't agree that you don't use your butt when walking. Rather, you can and, in my opinion, should walk with your glutes. In fact, if you use your glutes as the prime movers when you walk, you're more likely to not overstride and put too much force on your heels when walking. I talk more about walking, barefoot or otherwise, here.Now, I don't think that everyone must run. Some like it, some don't. And I don't agree that we're all meant to run long distance (Lieberman doesn't discuss that here, but it's something he and I chatted about). But it sure is compelling to see that we may be built so that we CAN run.What do you think?The content of this post does not constitute and is not intended to be a substitute for professional medical advice, diagnosis or treatment.

Khanh scaling the Stratosphere Hotel in his barefoot sandals by Xero Shoes

I dare you to run barefoot! Or bigfoot. Or both!

What inspires someone to take off their shoes and run barefoot?For Khanh Nguyen it was knee pain and the hope that barefoot running would help.Once he got started, in bare feet and in Xero Shoes, he was on fire. He's run 1/2 marathons, mud races and, most recently, he ran UP the Stratosphere Hotel in Las Vegas in his Xero Shoes. AND, he did it in our Bigfoot, the Xero Hero costume!Enjoy this really fun interview with Khanh, and see what motivates him to run (hint: his brother dared him!)

Proof that Bigfoot wears barefoot shoes - Xero Shoes

Bigfoot wears barefoot shoes? Yup.

Have you seen bigfoot?If you were in Las Vegas on March 2nd at the Stratosphere hotel, you probably did.In fact, you may have seen this mysterious barefoot beast climb the Strat!While most people who claim to see bigfoot have grainy, fuzzy pictures or video, we have high-resolution proof of his existence. And, even more, we have proof that Bigfoot wears barefoot running shoes. Xero Shoes, to be exact!Here's a pic of the legendary monster at the base of the Stratosphere (that's looking UP the building). You can see his barefoot footwear (and his elevation training mask, which scares off the easily upset).Then, just a short time later, Bigfoot was spotted at the top of the hotel! Apparently happy that he's avoided capture yet again.In reality, this is our friend and Xero Shoes athlete, Khanh Nguyen, dressed as Bigfoot, the Xero Hero. Khanh scaled the Strat as part of a fundraiser to support the American Lung Association. You can add your support by clicking here.

Does barefoot running cause calf pain?

Does Barefoot Running Cause Calf Pain? - Xero Shoes

People making the transition to running barefoot or in minimalist shoes sometimes experience calf pain or even calf injuries. They can also feel pain in their Achilles tendon.I have talked with plenty of people who assume this kind of pain is just part of the transition process from running in typical running shoes to running barefoot or in minimalist shoes.If you’ve heard this, too, I have good news for you:Pain isn’t a necessary part of the process!I like to say “calf and Achilles pain is optional” (if you know what to do).I am going to first give you an overview of why runners might experience calf pain in the first place before turning to barefoot running and why I think the conventional wisdom here is wrong.Why We Get Achilles Tendon and Calf Pain when RunningYour calf has a set of muscles (including the gastrocnemeus and soleus muscle) that connect to the Achilles tendon and provide both the power for pushing with your foot, as well as controlling how your heel comes down to the ground if you land on the ball of your foot.The most basic reason runners experience calf pain is overworking the muscles and tendons.This can happen for a variety of reasons. In some cases, it is because they were used to apply an amount of force the muscles are not used to. For instance, if you’re used to running on flat surfaces but then go for a run on a hill, your calf muscles are going to be working a lot harder than usual. This can also happen with a sudden increase in distance.In other cases, it isn’t that the force is too much but that it goes on for so long. To put it differently, the muscles are pushed past their point of endurance.Sometimes, a runner’s calf muscles have simply been asked to work before a proper warm up or stretch. Tight calves that are suddenly put to work places a lot of strain on the muscles.Whatever the reason, pain is your body’s way of telling you that your muscles need a rest, and that you probably need to use your calves differently once you’re feeling better.Sore calves are a normal effect of exercise and nothing to worry about. Severe calf pain, on the other hand, is an indication of a more serious problem. If you overwork your calf muscle, you risk injuries like a calf strain or even a calf tear. Muscle tears are painful and can require a long recovery process.In short, then, tendon or calf pain is an indication that you’ve overdone it in some way.Why People Assume Calf and Tendon Pain Are Just Part of Barefoot RunningWhen you run barefoot, you run differently than if you’re in typical shoes (get tips on how to run barefoot here). Generally speaking, runners who are used to thick, modern running shoes will tend to land heel first with their foot contacting the ground well in front of their body.Once making the switch to either no shoes or minimalist ones, most runners will probably stop landing that way. Why? Because it hurts to land on your heel!Instead, barefoot runners will tend to adopt a mid-foot or fore-foot strike pattern, landing with the heel initially off the ground. In that running form, the calf muscles act as shock absorbers, controlling the speed with which your heel comes down to the ground (or near it). This “eccentric” or “negative” loading can place greater demands on calf muscles and tendons than they used to.It makes sense, then, that transitioning to barefoot-style running could lead to overworking of the calf muscles and therefore to calf pain and soreness.Most people think the issue is that the calf muscles are too weak because of previous underuse and the solution is to make the calf muscle stronger.In other words, people believe that calf and Achilles soreness is practically inevitable when you try running barefoot, and that building strength is the eventual cure.But that story is missing something important.Why Calf and Tendon Pain Are AvoidableI say that it is missing something and not that it is totally wrong.It is true that barefoot running usually means a new (and more natural) running technique that can place more demands on the calf muscle.But this doesn’t need to lead to calf pain when running.The most common problem many runners have when they begin to run barefoot is that they simply use more effort than necessary when they run.Consider that there are two ways to keep your calf muscles from being overworked: to have stronger muscles for a given amount of work or to reduce the work required. Runners usually assume they need to do the first thing – build up their calf muscles with strengthening exercises.From what we’ve seen, having heard from tens of thousands of new-to-barefoot runners, the “secret” to reducing your odds of having calf pain is to do less and relax more.So let’s take a deeper look at this other option: to prevent calf pain or calf injury by reducing the amount of work you ask your calves and Achilles to do.The Common Mistakes Barefoot Runners MakeOkay, so how do we do less and relax more?It all comes down to form.New barefoot runners often have two other habits that put unnecessary strain on their muscles and tendons, putting them at risk of calf muscle injuries:Overstriding while landing on the mid-foot or ball of the footMost new barefooters hear that you should land on the ball of your foot, or on your midfoot.It’s true. BUT, the mistake many make is using the same form they have in regular shoes – landing with their foot in front of their body (“overstriding”), and then merely pointing their toes.When you land with your foot further in front of your body, you’re basically “putting on the brakes” which puts excessive force on your foot.If you point your toes to land on your forefoot, you use your calf and Achilles to decelerate and this amount of force is more than most people’s calves can handle. In fact, it’s more than the bones of your foot are made to handle so you’re also risking a stress fracture.Sure, getting freakishly strong may make that easier to do, but the correct solution is to “stop putting on the brakes” when you land by stopping your over-striding and, instead, placing your foot more underneath your body when you land.By not applying that breaking force, your calves don’t have to do as much work.One way to learn to land with your foot underneath you is by increasing your cadence – the number of steps you take per minute – without running faster. This quicker cadence makes it harder to overstride.There’s actually a recent study on this. Researchers found that runners with a history of recurrent calf strain injuries land with their heels further away from their center of mass.Pushing OffSimilarly, if you remove your foot from the ground by pushing off with your toes, you’re essentially doing bodyweight calf raises every time you take a stride… and even a short run would be more than your body can handle.Again, the solution isn’t to hit the gym to lift weights or cross train to improve your calf raise strength. It’s to LIFT your foot off the ground (instead of pushing) by flexing at the hip.I know that sounds weird, so let me give you an image to help it make sense:Imagine what happens if you stepped on a bee and it stung your foot… you wouldn’t try to push away from the ground since that would drive the stinger further into your sole. You would reflexively (faster and easier) pull your foot from the ground with a hip flex.You want to use that same hip flex to get your foot off the ground when you run. You’re still using your calf muscles, but not nearly as much as you do by “toe-ing off.”How to Find the Right Running Style that Won’t Lead to Tendon or Calf StrainIn order to use less effort, you’ll probably have to start with less running.That’s fine.Even when you make the adjustments I just described, barefoot running will have you using your lower leg muscles in new ways that will take some time to get used to.The key thing at this early stage to prevent calf injuries is to be patient and listen to your body. Calf tightness isn’t something to worry over. Make sure you are warming up with some calf stretches to keep loose.On the other hand, sharp pain in your feet or calves, shin splints, calf strains — these are all clear messages from your body that something isn’t right. You may even find that you are getting calf pain in your left calf but not your right calf. That can be an indication that you are getting it right with one leg but not yet the other.If you are willing to take it slowly and make adjustments, it is just a matter of time before you find the running form that will feel easy and fun.And you’ll find that you will be able to run your usual distances and times sooner than you think.By the way, it isn’t just calf pain that is a potential issue. Running injuries like plantar fasciitis and shin splints are common, and researchers suggest an important risk factor is increases in the volume or pace of training. Injury prevention requires respecting your body’s limits.By the time you figure everything out, you will probably have gained any extra strength you need.Barefoot Running…in Shoes? I have mentioned minimalist shoes in this article about running barefoot and calf pain. Maybe that confused you. If so, let me explain.Barefoot running is all about recovering a natural running form that allows our bodies to function the way they are designed. It seems obvious that doing what’s natural is better for our bodies. It’s also a lot more fun. It’s really more about how your feet move than about what you have on them.It’s about the form, not the footwear.There is a relationship between the two, however. Minimalist shoes (also called barefoot shoes) are designed specifically to give you the flexibility and feedback that let you maintain natural movement without you having to walk around in bare feet. So you can absolutely try barefoot walking or running without having to ditch footwear, as long as it’s the right footwear.We’ve put together a handy tool to help you find the perfect pair of barefoot shoes (or sandals) for you.
