The insoles below are designed for over-pronating feet. Over-pronation insoles provide arch support and control to keep your feet stable and in the proper position.
The outside of the heel makes initial contact with the ground. But the inward movement of the foot occurs at less than four percent (i.e., there is less rolling in than for those with normal or flat feet). Consequently, forces of impact are concentrated on a smaller area of the foot (the outside part), and are not distributed as efficiently.
In the push-off phase, most of the work is done by the smaller toes on the outside of the foot.
