Excessive elevation of the longitudinal (toe to heel) arch of the foot.
Alternative Names
High arch; High foot arch
Causes, incidence, and risk factors
Pes cavus or 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.
Expectations (prognosis)
The expectations depend on the presence of absence of underlying neurological conditions.
Prevention
People with highly arched feet should be evaluated for underlying neurological and orthopedic conditions. Recognition of other problems may help in preventing or modifying impending arch problems.
