After reading about this and similar research, instead of going out and buying an expensive new "barefoot-style" running shoe, I just pulled out my old, completely worn out running shoes out of the back of the closet and started wearing them running. They've lost almost all cushioning and are as flat as can be -- but 4-5 months later, I feel great.<p>I think like people have mentioned, the trick is really to just to land on the front/midsole of your foot not your heal. Then whatever crappy shoe you have will be fine.
