Supination, also known as underpronation, is the insufficient inward roll of the foot after landing. It may be the result of having a naturally high-arching foot, or it may also be caused by certain muscle weakness in your calves, ankles, or feet that are a result of ill-fitting running shoes, improper gait, or previous injuries. When a supinator runs, the outside of the heel of his/her foot hits the ground first, said Steven Weinfeld, MD, associate professor of orthopaedics at the Icahn School of Medicine at Mount Sinai and chief of foot and ankle surgery at The Mount Sinai Hospital. Because the foot does not sufficiently roll inward after landing, the force of impact remains concentrated on that one specific part of the foot. An easy way to tell if you're doing this regularly is if your running shoes wear out quickly and unevenly, with more breakdown on the outer side of the shoe. To check if your shoes have uneven wear, place them on a flat surface. If they tilt outward, supination is likely in play.
