What is Pronation?
This picture shows a view of the right foot as if looking at it from behind. As you can see in the picture the ankle is over pronating or rolling inwardly.
Pronation refers to the inward roll of the foot during normal motion and occurs as the outer edge of the heel strikes the ground and the foot rolls inward and flattens out. A moderate amount of pronation is required for the foot to function properly, however damage and injury can occur during excessive pronation. When excessive pronation does occur the foot arch flattens out and stretches the muscles, tendons and ligaments underneath the foot.
