This weekend's Wall Street Journal included John Hawks review of Daniel Lieberman's book " The Story of the Human Body".
From the article:
"The author, a Harvard evolutionary biologist, is a true expert in a system where architecture and history intersect: the human foot. He ably describes how behavior and anatomy can lead to foot injuries in long-distance runners. In his interpretation, the anatomy of the feet and legs are well suited for running, but in ancient cultures people never wore shoes or ran on pavement. These barefoot runners used a softer stride, landing springily on the ball of the foot instead of hard on the heel. Skipping the jolt of heel-strike helped to buffer the feet, legs and hips against repeated stress injuries. Today's runners train differently, counting on thickly padded shoes to absorb shock. By leaning on technology, runners face a new mismatch between anatomy and behavior. Padded soles and orthotic inserts perniciously treat the symptoms of foot injuries instead of building stronger feet."
