Pes cavus; High foot arch
High arch is an excessively raised arch (also called instep) on the bottom of the foot. The arch runs from the toes to the heel. It is also called pes cavus.
High arch is the opposite of flat feet.
High foot arches are much less common than flat feet. However, they are more likely to be associated with an orthopedic or neurological conditions. Neuromuscular diseases that cause changes in muscle tone may lead to the development of high arches.
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 the toes (metatarsals). This condition generally makes it difficult to fit shoes. In addition, those with high arches usually need foot support. A high arch may cause significant disability.
