10 A 1987 study by Steven Robbins and Adel Hanna analyzed how the long arch of 17 runners changed when they trained barefoot over a period of 4 months. The study found that the long arch decreased in length by an average of about 1/4 inch. The researchers said this change was due to the activation of foot muscles when barefoot that are usually not working when wearing shoes. They maintain that foot musculature allows the foot to dampen impact and suggest that this adaptation may remove stress from the plantar fascia.

11 Going barefoot is now being used to cure plantar fasciitis. And it works!

14 Natural gait is biomechanically impossible for any shoe-wearing person. It took 4 million years to develop our unique human foot and our consequent distinctive form of gait, a remarkable feat of bioengineering. Yet, in only a few thousand years, and with one carelessly designed instrument, our shoes, we have warped the pure anatomical form of human gait, obstructing its engineering efficiency, afflicting it with strains and stresses and denying it its natural grace of form and ease of movement head to foot. -Dr. William A. Rossi, Podiatry Management, 1999

15 One study shows that compared to running barefoot, running in conventional running shoes increases stress on the knee joints up to 38%. Michael Warburton's 2001 review of barefoot running in the journal Sports Science concluded that running barefoot is associated with a substantially lower prevalence of acute injuries of the ankle and chronic injuries of the lower leg.

16 Athletic Footwear: Unsafe Due to Perceptual Illusions, published in a 1991 issue of Medicine and Science in Sports and Exercise. 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). According to another study, people in expensive cushioned running shoes were twice as likely to suffer an injury than were people who went running in hard-soled shoes.

17 Dr. Bernard Marti of Switzerland s University of Bern analyzed 4,358 runners that ran a 9.6 mile road race. He found that the runners wearing top of the line shoes were 123% more likely to get injured than runners in cheap shoes. Runners in shoes that cost more than $95 were more than twice as likely to get hurt as runners in shoes that cost less than $40.

18 Elite running programs all over the world are now having their athletes train barefoot at least part of the time. Their race times are faster because the runners who train this way have feet that are stronger all around and able to work more efficiently even when wearing shoes.

19 Rush University study: The impact on knees is 12% less in bare feet than in padded shoes. When we plant our feet harder and they can t work as springs, the impact is carried up to our knees, hips and back. Those structures have to absorb the impact The back, knees and hips also have to take over motion control that barefoot feet take care of naturally and much more efficiently

20 January 4, 2010 issue of Science Daily reported a study of joint stress in people on a treadmill wearing shoes vs. barefoot. Running shoes cause an average of 54% increase in hip torque and a 38% increase in knee torque compared to barefoot. This is 2 times worse than the joint stress caused by high heels.

23 It s like driving a stick shift after years at the wheel of an automatic you suddenly feel in control of an intricate machine, rather than coasting on cruise control. - Adam Sternberg
