To Be Barefoot, or Not?

Updated: Jul 1, 2023

Why kick off your shoes and run/walk barefoot?

Humans have been running/walking barefoot (and in minimal footwear) for about two million years. It is our natural state. Our feet evolved to function without footwear. Shoes often abuse our poor misaligned, claustrophobic feet.  It is almost hard to believe we treat the foot, which literally unites us to the earth, so badly.  I admit some of us go through lots of hoops drawing attention to our feet. With pretty pedicures, high-end heels (4 inch Christian Louboutins) and trendy sneakers that cost over $500 (think Prada), our feet would, on the surface, seem pampered. Not the case by a long shot, so say I. We jam shoes on our children the minute after taking their first steps. From that point on, we barely take them off until the day we die (and some of us are even buried with shoes!).

Ever try to put a shoe on a baby or even a family dog? They can hardly remove the offending shoe or booty fast enough. It is actually quite funny and frustrating to watch. It is an instinct to be barefoot.  Until about age 10, most children still have soft, malleable feet.   Not to mention they are getting larger all the time and literally pushing up through the seams. Kids’ feet are not just smaller versions of ours; they tend to be wider across the toes and mostly cartilage (which is gradually replaced by bone). Children’s footwear is modeled to be smaller versions of adult ones. Most shoe companies design shoes with pre-defined shapes and overlook the natural architecture of the human foot. This is especially true when it comes to shoes for kids. Rigid and malformed shoes directly affect how a child’s foot bones and arch will shape. Our toes are supposed to be spread out, almost in a “v” shape.  Instead, most of us have crunched and smooshed in feet with little or no independent control of our toes. Our feet become the shape of the shoes we wear.

For various reasons, sneaker companies are always convincing us to buy snug-fitting shoes for our toddlers (and us). A growing child’s foot will satisfy all of its developmental requirements by simply playing, jumping, and running without shoes.

Udaya B. Rao, Benjamin Joseph, (1992) “The influence of footwear on the prevalence of flat foot: A survey of 2,300 children”, Journal of Bone and Joint Surgery, Vol. 74‚ No. 4. pages 525-527.

  1. Findings: An Elevated heel of any height on a child’s shoe shortens the Achilles tendon. This marks the beginning of permanent tendon shortening.  Flat foot was most common in children who wore closed-toe shoes, less common in those who wore sandals or slippers and least in the unshod. The study suggests that shoe-wearing in early childhood is detrimental to the development of a normal longitudinal arch.

Dr. William A Rossi, (2002) “Children’s Footwear: Launching Site for Adult Foot Ills,” Podiatry Management, pages 83-100.

  1. Findings: Slimmer and more flexible children’s shoes do not change foot motion as much as conventional shoes and should generally be recommended for healthy children.

When my son isn’t running around barefoot, he rocks a pair of pink or aqua blue VIVOBAREFOOT shoes.  He also wears “zero drop” sandals like Huraraches or scuba socks.  It is important to find a pair with no heel, thin soles, lightweight, and a big toe box in looking for shoes.  Let your feet feel the ground and function like they were evolved to work.

I really love this next video.  It is a grainy copy of Alan Watts, an intellectual Eastern philosopher from the ’70s (and yes, he did like his LSD), pontificating on ideas of work and play concerning running:

Americans do very little without shoes. Lots of people even take showers with shoes! We have been conditioned to be afraid of the dangers of being barefoot. However, the majority of those fears are unfounded. To give one example, the chances of getting a bacterial and/or fungal infection is increased exponentially by wearing socks and shoes. A dark, moist, warm environment that a shoe provides is a perfect breeding ground for such infections.  Contrary to popular belief, habitually unshod feet are rarely malodorous and/or subject to infection.  Many of our foot problems can be traced back to our obsessive shoe-wearing; bunions, hammertoes, plantar fasciitis, etc. I believe a barefoot person’s feet will be stronger, more agile, balanced and less prone to injury/infection than the shod foot.

Skilled and habitual barefoot runners will land on their forefoot first and then heel plant (except for sprinting, which has no heel strike). This is how most animals run in the wild. Athletic shoes tend to compromise our gait. Wearing modern shoes influences us to run and walk in an unnatural form; landing hard on the heel, taking extra long strides, and integrating a rolling action to the toes. These movements are compromises and it is quite painful to progress this way barefoot.  It's the body’s way of telling us not to do it, whereas cushioned shoes confuse and change our whole locomotive pattern.  Running can essentially be distilled into a series of one-leg jumps. Stand up, go ahead and do it….I’ll wait.   Find a hard surface (not carpet) and hop up and down on one leg but be sure to land directly on your heel (like you do while running in sneakers). Feels wonderful, right? Of course not!  It has been shown that heel striking will increase the forces upon one’s foot and lower leg while running. Analysis shows that barefoot runners who forefoot strike even on hard surfaces generate smaller collision forces than shod heel-foot strikers.

The modern running sneaker and walking shoe have wreaked havoc on the human foot. They have several common construction features that pose potential dangers. In my opinion, these three features listed below are the most pernicious.

1- High thick heels (most sneakers have 1/2” to 2” heel above the lowest part of the foot) may lead to:

  1. Shortened and weakened calf musculature

  2. Excessive strain on the plantar fascia and Achilles tendon

  3. A bodyweight shift forward changes your natural upright posture

  4. Increased impact forces -because you have to step down harder to feel the ground

  5. Longer strides in front of your center of gravity increase the shear forces on your knees, hips and ankles

  6. Reduces the shock absorbing and elastic properties of your arches

 2- Curved up narrow toe boxes (toe springs):

  1. Toes cannot naturally splay out (a function for balance and proprioception) when you step down

  2. Toe joints stay in an extended position, which can lead to adaptive shortening

  3. Toe dexterity is weakened

  4. It may lead to hammertoes and/or bunions

  5. Crowds toes, which in time may cause permanent faulty alignment

  6. Flexing motion (gripping) of the MTP joints are weakened (specifically the big toe)

  7. Toes are meant to grip the ground. The curved “toe springs” hold your toes up, preventing most gripping action

  8. The first MTP (big toe) is restrained from doing its natural push-off and in turn, causes a “roll” off the forefoot and/or pivot on the smaller MTPs.

 3- Arch Support:

  1. Prevents natural pronation

  2. Inhibits normal function of your arch

  3. Increases compensatory patterns, which may weaken the foot and knee

  4. Increases your chances of spraining an ankle

Since the advent of the modern running shoe in 1972 (Nike), we have not seen injury rates go down; in fact, some studies have shown they have gone up. Yet somehow, sneaker companies have been spending billions of dollars on marketing, research and development to make “better shoes” (Honestly, I don’t believe in a grand conspiracy by the shoe companies to hobble society….their motives are more simple, produce shoes that turn a profit). In a paper for the British Journal of Sports Medicine in 2008, researchers revealed no evidence-based studies that demonstrate running shoes make you less prone to injury. Not a one! In fact, some studies show that heavily cushioned expensive footwear causes more injuries than their inexpensive less cushioned counterparts! Your joints' impact while running can be several times your body weight and a heel cushion will do little to ameliorate those forces.

“You can cover an egg with an oven mitt before rapping it with a hammer, but that egg ain’t coming out alive.”- Christopher McDougal author of “Born to Run”.

Steven E. Robbins and Gerard J. Gouw. “Athletic footwear: unsafe due to perceptual illusions,” Medicine and Science in Sports and Exercise, 23(2), 1991, pp. 217-224.

  1. Findings: Wearers of expensive running shoes that are promoted as having additional features that protect (e.g., more cushioning, ‘pronation correction’) are injured significantly more frequently than runners wearing inexpensive shoes (costing less than $40)”.

S Robbins, E Waked. “Hazard of deceptive advertising of athletic footwear”. British Journal of Sports Medicine (1997);31:299-303.

  1. Findings: Shows that runners who wear top of the line shoes are 123% more likely to get injured than runners in cheap shoes (which have less cushioning and support).

The pictogram below shows the correct way to walk barefoot.  When you walk with shoes your gait changes.  However, you can learn to walk better in shoes by re-learning some basic skills:

According to research by Harvard professor Dr. Dan Lieberman,  humans evolved into expert barefoot endurance runners out of necessity. His research makes a cogent argument for the normalcy of human barefoot running. As animals, we are pitifully slow sprinters. This is how we compare:

Cheetah – 70 mph

Antelope – 61 mph

Deer – 30 mph

Cat – 30 mph

Greyhound dog – 39 mph

Horse – 55 mph

Usain Bolt – 27 mph (fastest human on record but most of us are topping out at the blistering speed of 14-17 mph)

Due to our anatomy and bipedal nature, we are exceptionally capable of endurance.  It is widely accepted that humans are the best long-distance runners in the entire animal kingdom.  Our survival as hunter-gatherers depended on our ability to outwit, chase, and catch prey. Moreover, scant evidence shows humans used projectile weapons until fairly recently (about 50k years ago). Therefore, we most likely used our bigger brains and better endurance skills to catch prey. Persistence hunting (which seems totally insane on the surface) is the practice of running down and tracking prey, usually over long distances, to the point of the animals’ total exhaustion.  In some cases, the animal drops dead of fatigue or submits to capture.   A few tribes around the world still practice this skill. Obviously, this was not our only way (or even primary way) of getting food. Lieberman’s theory shows how barefoot humans probably ran long distances to survive. The ones who were the most successful hunters and least injured lived to become our ancestors.

Running barefoot is not for everyone. If you have foot abnormalities and/or dysfunctions, you may not benefit from being barefoot. Perhaps you are one of the few, lucky, avid runners who are injury-free? If that is the case, I wouldn’t change a thing. Stick with what works.  On the other hand, if you are interested in running barefoot, you will need to stick to a progression schedule and re-learn the skill.  In my next post, I will document the process.

I have a love affair with skepticism and contrarianism, thus compelled to detail the primary arguments against barefoot running. Until more research is available, it’s hard to prove sneakers are outright harmful to most people. Here are the pros and cons often discussed and observed in regards to barefoot running/walking:


1- Just because barefoot running and walking is a “natural” part of human locomotion doesn’t mean it is good. The animal kingdom is rife with examples of animals that evolved detrimental traits. Including Homo Sapiens and our damned appendix, wisdom teeth, male nipples, etc.

2- There is a lack of research showing that barefoot running is less injurious than shod running. In fact, some studies show that barefoot running (and heel striking) can be more deleterious.

3- Debris and sharp objects may bang-up and cut your feet (this is why people wear minimal shoes).

4- My feet will get dirty and callused. I can definitely attest to this one.

5- Barefoot running hurts. (If you are taught correctly and break in slowly, it should not hurt  but a little discomfort is expected).

6- It is just a fad (albeit a two million-year-old fad).

7- Due to deformities and or prior injuries some people will not benefit from barefoot running/walking and may in fact, cause themselves further injury.

8- Habitually barefoot feet are much different looking than our pampered western feet. The foot is usually bigger, with no discernible arch, splayed toes, leathery soles and all-around Hobbit-like.


(The research on the benefits of barefoot running/walking is inconclusive yet below, I list some anecdotal and scientifically observed advantages of natural barefoot running):

1- Strengthens the foot’s arch and toes

2- Helps elongate one’s calf musculature and increase the flexibility in the ankle complex

3- Improves the foot’s dexterity

4- Improves the lower leg and foot’s proprioception

5- Can help people improve their running times

6- It costs less energy (the weight of the shoe can drastically change your gait and increase your metabolic demands) and therefore may allow you to run longer

7- It helps you become more aware of your surroundings (and closer to nature) and improve the tactile feeling in your feet

8- Less bad forces put upon your lower leg and foot

9- You can spread and expand your feet more, giving greater control to the foot musculature

10- Foot ailments like bunions, hammertoes, ingrown toenails and neuromas may be prevented by living barefoot

11- Balance and coordination may be improved

12- Societies that live barefoot enjoy almost injury free running and suffer very little from common Western foot ailments (BUT, these societies tend to lack Park Avenue sports medicine doctors and podiatrists—remarkably, there are very few complaints of ingrown toenails (etc) and the medical data is even more uncommon!).

13- It is just more fun and so cool to be barefoot! (this is, of course, a peer-reviewed scientific fact 🙂

In the case you are a data wonk, listed for your perusal are a few more important studies documenting the benefits of barefoot running (and yes, I could also provide you with studies depicting the advantages of athletic shoes — but most seem to be sponsored by Nike, Reebok, Asics, etc.):

1- Robbins, S; Hanna A (1987). “Running-related injury prevention through barefoot adaptations”. Medicine and Science in Sports and Exercise 19 (2): 148–156.

  1. Findings: Analyzed the longitudinal (medial) arch of 17 habitually shod runners and how it changed when they trained barefoot over a period of 4 months. It was found that this arch decreased in length by an average of 4.7mm. Authors contend this change is due to activation of foot musculature when barefoot is usually inactive when shod. They maintain that foot musculature allows the foot to dampen impact and remove stress from the plantar fascia.

2- Kerrigan, D. Casey; Franz, Jason R.; Keenan, Geoffrey S.; Dicharry, Jay; Della Croce, Ugo; Wilder, Robert P. (2009). “The Effect of Running Shoes on Lower Extremity Joint Torques”. PM&R 1 (12): 1058–63.

  1. Findings: Shows that compared to running barefoot, running in conventional running shoes increases stress on the knee joints up to 38%, although whether this leads to higher rate of heel injuries is still not clear

3- Lieberman, M Venkadesan, WA Werbel. “Foot strike patterns and collision forces in habitually barefoot versus shod runners”, Nature, 2010.

  1. Findings: Kinematic and kinetic analysis show that even on hard surfaces, barefoot runners who forefoot strike generate smaller collision forces than shod rear-foot strikers. Forefoot and mid-foot-strike gaits were probably more common when humans ran barefoot or in minimal shoes, and may protect the feet and lower limbs from some of the impact-related injuries now experienced by a high percentage of runners.

4- C Divert, G Mornieux, P Freychat, “Barefoot-Shod Running Differences: Shoe or Mass Effect?” Orthopedics & Biomechanics, Int J Sports Med 2008; 29(6): 512-518.

  1. Findings: Stride frequency, anterior-posterior impulse, vertical stiffness, leg stiffness, and mechanical work were significantly higher in barefoot condition than shod. Net efficiency, which has metabolic and mechanical components, decreased in the shod condition. The mechanical modifications of running showed that the main role of the shoe was to attenuate the foot-ground impact by adding damping material. However, these changes may lead to a decrease of the storage and restitution of elastic energy capacity, which could explain the lower net efficiency reported in shod running.

5- Kerrigan DC, Franz JR, Keenan GS, et al. The effect of running shoes on lower extremity joint torques. PM R. 2009;1(12):1058-1063.

  1. Findings: Increased joint torques at the hip, knee, and ankle were observed with running shoes compared with running barefoot. Disproportionately large increases were observed in the hip internal rotation torque and the knee flexion and knee varus torques. An average 54% increase in the hip internal rotation torque, a 36% increase in knee flexion torque, and a 38% increase in knee varus torque were measured when running in running shoes compared with barefoot.
