Pes cavus; High foot arch; High instep
High arch is an arch that is raised more than normal. The arch, or instep, runs from the toes to the heel on the bottom of the foot. It is also called pes cavus.
High arch is the opposite of flat feet.
High foot arches are much less common than flat feet. They are more likely to be caused by a bone (orthopedic) or nerve (neurological) condition.
Unlike flat feet, highly arched feet tend to be painful because more stress is placed on the section of the foot between the ankle and toes (metatarsals). This condition can make it difficult to fit into shoes. People who have high arches usually need foot support. A high arch may cause disability.
