What is pes cavus?

Pes cavus, which is also known as high-arched foot, is characterized by an excessively elevated arch on the inside of the foot. When the person is standing, most of the weight is on the back and the ball of the foot.

High arched feet can be idiopathic, which means there is no known cause. It can also be associated with neuromuscular conditions such as cerebral palsy, spinal tumor, Charcot Marie Tooth disease, poliomyelitis and Friedreich's ataxia.
