Well padded ba mga five-finger shoes? It might not be good for you if you're an under/over pronator.
i watched a Modern Marvels episode about shoes. It said they were able to trace the beginnings of shoes by studying the bones on the feet -- i.e. bigla daw lumiit once man started wearing shoes. Makes sense naman, your body adjusts to your environment routine, the more stress a certain part undergoes, the more solid the muscles, bones, ligaments etc become. So i guess me sense yung sinabi niya.
Kaso, if you overtrain naman, or use equipment that's not suited for you, you get injured, sometimes permanently. That doesn't do you any good either
Better ask a sports doctor or something for the real deal. imho if there were any truth to barefoots being superior for running, all the pros would be wearing them.
