What is Pronation? 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.
All feet must do this and do it well in order to minimize the forces that the body has to deal with during walking or running, and also to create the lever that is needed for propulsion. It is the excessive pronation that has been considered a great offender in many of the above referenced conditions. This is when the foot remains in pronation for a longer than normal period of time. This also is what most people try to correct, and often do so improperly.
