Over pronation of a person's feet is fairly common. This happens when you walk and you have "flat arches" or "no foot print." This condition can put a strain on muscles, tendons, and ligaments. Over pronation can be caused by genetics or gradually over time from "wear and tear." Overpronation can increase injury risk, especially when wearing poor fitting shoes. Treatment options include orthotics, good shoegear, and sometimes medication or injections. Rarely a patient would have to endure surgery.
