 Keep Your Feet From Getting Lazy

"Shoes often protect the feet so much that certain foot muscles get lazy because they're not being used," said James DeMarco, running coach and sports store owner.

That's why more people than you'd think have taken to running in bare feet. Marathon runners from Kenya do it all the time, but in the United States you're most likely to see a barefoot runner on the beach. Still, there are those who venture to other areas like grassy fields and even hiking trails.

If you're thinking that running barefoot sounds strange, consider the findings of Michael Warburton, a physical therapist in Australia. In a 2001 research paper he wrote that running barefoot decreases the likelihood of ankle sprains and chronic injuries, such as plantar fasciitis. And, wearing shoes actually increases the risk of sprains because they make runners unaware of the foot's position.

It's not as far-fetched as it may sound -- Nike has just released the Nike Free, a "shoe that lets your foot run free on any surface." It's designed to mimic the effects of running barefoot. According to Nike, "Studies show that barefoot training leads to stronger feet, that stronger feet lead to a stronger body, and that natural movement enhances agility."
