"We found no scientific basis for choosing running shoes based on foot type," said Bruce Jones, M.D., injury prevention program manager at U.S. Army Public Health Command (Provisional), Aberdeen Proving Ground, Md. "Our findings have surprised not just military decision-makers -- many of whom run to stay fit -- but runners in general."

Popular running and sports medicine literature recommends that people with high arches should choose cushioning shoes, those with normal arches should choose stability shoes, and those with flat feet should choose motion-control shoes, Jones explained. The literature says that such shoes will compensate for the way these foot types strike the ground during running and lessen injuries to the legs and feet.

"This seemed to many of us to make sense," said Jones, a long-distance runner for many years. "But when we looked at it in multiple, scientific studies, it turned out to be a sports myth."
