I'm hearing a lot about barefoot running lately. Active.com and Runner's World have posted articles stating there's a difference in the way your foot strikes the ground, minimizing impact. So I tried it. I ran a couple laps around a school soccer field. Besides my feet being cold/numb, I couldn't feel any difference. Though today, the bottoms of my feet are tender and my ankles feel stretched.
I have a definite concern that I might step on something sharp or something squishy.
