Study: High heels better than running shoes - Science Fair - USATODAY.com

Study: High heels better than running shoes - Science Fair - USATODAY.com: "Walking in high heels is easier on your knees and ankles than jogging in running shoes, report researchers Monday in the journal PM&R, and bare feet might be best.

The injury, function and rehabilitation study led by D. Casey Kerrigan of JKM Technologies LLC in Charlottesville, VA, a team handed 68 young adult runners, 37 of them women, running shoes and observed their running motions in treadmill and video studies. All of the runners regularly ran at least 15 miles a week.

While the shoes protected the runner's feet well, they put excessive strain on hip, kneee and ankle joints, found the study authors. Knee joint twisting was about 38% higher than running barefoot, for example.

“Remarkably, the effect of running shoes on knee joint torques (twisting) during running that the authors observed here is even greater than the effect that was reported earlier of high-heeled shoes during walking,' Kerrigan says in a statement.

“Reducing joint torques with footwear completely to that of barefoot running, while providing meaningful footwear functions, especially compliance, should be the goal of new footwear designs.”"
