Supination of the foot occurs when the body’s weight rolls onto the outer edges of the feet. In a normal gait, the foot should roll inward a bit (pronate) so that the weight is on the ball of the foot and you can push off the big toe.

If you supinate, most of your weight falls on the outside of your foot and you push off from your outer toes instead. If the mechanics of your foot are a little bit off, it can throw off the alignment of your entire body. Excessive supination of your feet can lead to back and hip pain, stress on the knee, ankle injuries, and inflammation of the sole or Plantar Fasciitis.
