High-arched feet are less common than flat feet but are more likely to cause pain because of the increased stress put on the metatarsals, the long bones connecting the toes to the back of the foot. Excessively high arches may be inherited or acquired as a result of orthopedic or neuromuscular disease. In addition to pain, they can cause weakness and fatigue and make it difficult to find shoes that fit. People with high arches may need special orthopedic shoes or orthotics for support when standing, walking or running.
High arches are visible as a hollow instep during standing and are normally diagnosed by simple physical examination. Diagnostic tests, however, such as X-rays, MRIs, and electromyography (EMG), may be administered to detect any other disorders. High arches may not necessitate any medical treatment, although orthotics to support the foot may make individuals with this condition more comfortable. Only in extreme cases is reparative surgery considered.
