Pes cavus is a foot condition characterized by an abnormally high arch. This means that the arch of the foot is raised more than usual, which can lead to an uneven distribution of weight across the foot. People with pes cavus may experience discomfort or pain in the foot, ankle, or even the knees and hips due to the altered biomechanics. The condition can be caused by various factors, including genetics, neurological disorders, or injuries. Treatment options often include custom orthotics, physical therapy, and in some cases, surgery to correct the foot's structure and improve function.
