MD Podiatrist Discusses Supination

If you’re someone who tends to put extra pressure on the outer parts of your feet while walking or running, your feet supinate. Supination happens when your weight rolls to the outside edges of your feet. It’s associated with people who have high arches, says Dan Michaels, DPM.
“If someone has a high foot arch, the arch doesn’t flatten out when standing,” Dr. Michaels says. “Supination can be a result of genetics; it’s also from specific muscles overpowering others in your legs and feet.” For example, tight posterior tibial muscles (deep muscles in the backside of your lower leg) overpowering weak peroneal muscles can contribute to supination, he says.
