A high-arched foot can cause someone to have too much weight on the ball and heel of the foot when he or she is walking or standing. The heel of the foot is tilted inward and leads to an unstable foot. Therefore, a high-arched foot can increase the risk of getting an ankle sprain.
One may experience symptoms, such as pain when standing or walking and on the ball, side or heel of the foot one may find calluses. Also, hammertoes (bent toes) or claw toes (toes clenched like a fist) may be present. In some cases, one may drag his or her foot when he or she takes a step due to the weak muscles of the foot and ankle. This is known as foot drop. Therefore, custom orthotics can be used to help treat a high-arched foot because it gives us stability and acts as a cushion for the foot.
