Pes cavus foot is a foot with a high arch, one higher than normal. At first glance, a pes cavus foot may appear ‘prettier’ than a normal foot; but the distribution of the compressive forces of the foot on a high-arched foot is abnormal. This results in greater forces placed on the ball of the foot and on the heel. Pain may occur in any part of the foot as a result of this condition. Cause A pes cavus foot may develop as a result of neurological disorders and infectious disease such as polio, stroke, cerebral palsy, and spina bifida. Charcot-Marie-Tooth Disorder may also be related to the development of a pes cavus foot. Pes cavus may also be congenital. Babies are born with flat feet and the arches develop over time. During the development phase, pes cavus could result. A high arched food can lead to additional foot disorders such as Achilles tendonitis or plantar fascitis as well as hammer toes, corns and calluses. Treatment and Prevention Supportive shoes with custom orthotics is essential to the relief of pain associated with a pes cavus foot. Orthotic inserts that cushion the foot along with heel supports usually benefit the foot a lot. For over-the-counter insoles, consider a high arched orthotic or sensitive foot insole. Prevention of other foot disorders by the proper choice of shoes with a wide toe box and high toe box are essential.
