The arches of the foot are formed by the tarsal and metatarsal bones and, strengthened by ligaments and tendons, which allows the foot to support the weight of the body in the erect posture with the least weight.
Like some cases of flat feet, high arches may be painful due to metatarsal compression; however, high arches? particularly if they are flexible or properly cared-for?may be an asymptomatic condition.
Rigid flatfoot, a condition where the sole of the foot is rigidly flat even when a person is not standing, often indicates a significant problem in the bones of the affected feet, and can cause pain in about a quarter of those affected.
Most flexible flat feet are asymptomatic, and do not cause pain.
Pronation is the inward roll of the foot while walking or running. Another way to look at pronation instead in terms of the degree of inward roll is in terms of where the foot pushes off at the end of each step, or at the end of the gait cycle.Overpronation is usually associated with many overuse injuries in running including medial shin splints, and knee pain.
