When you take a normal step, the first part of your foot to touch the ground is your heel. Your weight is then transferred to the long bones of the foot, or metatarsals. The foot rolls from the outside inwards, or pronates, to distribute the weight across the bones. It starts at the back of the outside metatarsal, moves to the front of the inside metatarsal, and ends with a push-off from the big toe. Neutral pronation means that weight is distributed evenly as the foot rolls inwards. Some people are overpronators. This means the foot rolls too far inwards as weight is transferred from the heel to the metatarsals to the big toe, and distributed unevenly with too much weight on the big toe. Sometimes the arches collapse or the ankle rolls inwards. People can also be underpronators. This means the foot does not roll in enough as weight moves from the heel to the long bones, with too much weight being borne on the outside of the foot.
