The Bare Necessities: From Shoes to Barefoot

Try this: go outside and run around the block (ok, just jog). Most of you probably would have donned a pair of cushioned, foot correcting sneakers before walking out of your house. This is typical for many 21st century humans who want to make sure they don’t get injured while braving the pavement. Shoe stores are filled with hundreds of brands and models specifically designed to combat some kind of foot problem when you’re running. However, current studies have indicated that the ideal thing to wear for running might not be a pair of arch supported or ankle stabilizing sneaker anymore. Why it took researchers so long to run down the stats on how our bones, muscles, and ligaments adapt to the different surfaces when we walk or run and how that changes our whole body’s physiology is probably because they were wearing the wrong shoes too. Barefoot running, and even walking, can be traced back to our great Paleolithic ancestors and now companies like Vibram, Newton, Saucony, and Nike have flooded the markets with their shoes that claim to resemble running barefoot, without the scrapes and bruises.

Through advanced technology, shoe manufacturers have been able to design sophisticated footwear to prevent our feet from over pronating (stability control), pounding the ground with too much force (shock absorbers like air sacs, springs, and more cushion), and dropping our arches (arch support). These new methods for controlling our feet’s movement are more of a “crutch” than a treatment. In the last decade, studies on barefoot running have sent many health and sports magazines to track down experiences of this phenomenon. The leading magazines for running enthusiasts, Runners World and Running Times, have both printed a number of articles on the benefits of minimalist shod and barefoot running. A study conducted by Dr. Daniel E. Liberman, professor on Human Evolutionary Biology at Harvard University, pointed out the natural adaptations of the body as a person runs barefoot compared to a shod runner. When a runner has the ability to allow his or her foot to move freely when making contact with a surface, the proprioceptors within the foot muscles respond and adapt to the surface, thereby recruiting the correct set of muscles to prevent injury from occurring. With foot correcting sneakers, the foot has little awareness of the surface with which it is making contact, causing a incorrect running style, and therefore, the recruitment of different muscles are needed, resulting in common running injuries.

Here’s an experiment for you to try. Go to your local high school track, or if you have a clean section of road nearby, run ten yards down the track or road. Then take off your shoes and repeat. If you compare the two running styles next to each other (shoes and barefoot), one would see that our running style quickly changes when our foot hits the ground. When we run with shoes, because of the cushion in the heel, we’re more prone to have our heel strike first. Yet once our shoes come off, our body shifts to the mid or front part of our foot where our legs can suddenly work together like a spring and propel our bodies forward. This also prevents our heel from stabbing the ground and hurting the bony surface. “The amount of reaction force generated in the foot and leg also decreases, explains Dr. Liberman. A look at his figure (Fig. 1) shows that there is much less reaction force when someone uses a front foot strike with a short stride, which is common when running barefoot compared to a rear foot strike (heel to toe style).

This is not to say that everyone should go out today, ditching those old cross-trainers and run freely. Running barefoot takes time, as is common in any form of muscle training. Muscles, when stressed, need time to recover and adapt. Also, unlike the humans of 100,000 years ago who didn’t grow up with something on their feet from birth, have paved roads, and broken glass shards, the 21st century human must train our feet longer for the conditions of today’s environmental surfaces. Vibram’s FiveFingers, Nike’s Free Run, Saucony’s Kinvara 2 are minimalist shoes that allow your feet the freedom to move like being barefoot but with a little added protection between your feet and the pavement. If you want to be true to your natural instincts, train your body to run sans shoes. Start on grass or sand before transitioning over to tougher surfaces. Don’t run too long if you’re inexperienced because the muscles in your foot will quickly fatigue. Running a couple times a week barefoot will make your feet adapt to the surface and overtime, you’ll have the ability to run away without any injuries.
