A term used to describe when the arch of the foot is higher than usual.

Sometimes, pes cavus is caused by diseases that affect the function of muscles. These diseases are due to problems with nerves and muscles. Other causes can include trauma and a condition at birth in which the foot is turned inward.

Pes cavus may not cause any pain. But when it's linked with a health condition, it may cause limited range of motion, physical changes and tight heel cords in the foot.

Pes cavus treatment may include stretching, strengthening of foot muscles, and orthotics to support the arch and keep the foot in the right position. Depending on the cause of pes cavus, bracing or surgery may be needed.
