A new study suggests that running shoes might actually exert tension which can damage your knees, hips and ankles, more so than walking with high heels!
A new study by D. Casey Kerrigan aiming to “determine the effect of modern-day running shoes on lower extremity joint torques during running” appeared in the December issue of PM&R Journal. The conclusion of the study was that running shoes exerted more stress on knee, hips and ankle joints compared to running barefoot or even walking with high heels.
“Remarkably, the effect of running shoes on knee joint torques during running (36%-38% increase) that the authors observed here is even greater than the effect that was reported earlier of high-heeled shoes during walking (20%-26% increase). Considering that lower extremity joint loading is of a significantly greater magnitude during running than is experienced during walking, the current findings indeed represent substantial biomechanical changes.”
To me these findings are quite shocking since I was under, what seems to be false, impression that running shoes gave me better support and exerted less tension to the joints than running barefoot. Running barefoot is not really a suitable alternative to me though, since it would probably hurt and leave me with quite the rough skin under my feet. But it seems running shoe designers have a job to do!
Please start making running shoes which simulates the natural act of running barefoot, because I really enjoy running.
I was just informed me about a web page called Barefootrunningshoes which serves as “an information hub on many of the popular barefoot running shoes that are currently available as well as related products and accessories”. Could be helpful if you’d like to get shoes which resembles that of running barefoot. Thanks Kate!
