Pes Cavus (High Arch Foot)

Synopsis

High arch is the opposite of flat feet. Highly arched feet are much less common than flat feet and more likely to be associated with an abnormal orthopedic or neurological condition. Neuromuscular diseases that cause changes in muscle tone may be associated with 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). Highly arched feet may make it difficult to fit shoes, generally require a foot support, and can cause significant disability.

Symptoms & Signs

• the foot length may be shortened because much of it is taken up in the arch

• difficulty fitting shoes

• foot pain associated with walking, standing and running

Prevention & Treatment

People with highly arched feet should be evaluated for underlying neurological and orthopedic conditions. Identifying these other conditions may help prevent or lessen impending arch problems. Corrective shoes may help to relieve pain and can improve walking. This includes orthopedic modifications to the shoes, such as an arch insert and a support insole. Surgery to flatten the foot is sometimes necessary in severe cases.

Prognosis (Expectations)

The expectations depend on the underlying neurological condition, although in mild cases, appropriate shoewear and arch supports may provide excellent relief.
