What is over pronation of the foot? Pronation occurs as weight is transferred from the heel to the forefoot when walking or running and the foot naturally rolls inwards. A certain amount of this is natural but in many people the foot rolls in too much or over pronates. When standing, pronation occurs as the foot rolls inwards and the arch of the foot flattens, hense the term often used to describe someone who over pronates as having 'flat feet'. Pronation is a normal part of the gait cycle which helps to provide shock absorption at the foot.
