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. Highly arched feet may make it difficult to fit shoes, generally require a foot support, and can cause significant disability. This includes orthopedic modifications to the shoes such as an arch insert and a support insole.
Surgery is sometimes necessary in severe cases.
The expectations depend on the presence of absence of underlying neurological conditions. Call your health care provider if you suspect having high arches. 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. The information provided herein should not be used for diagnosis or treatment of any medical condition.
