Pes cavus (in medical terminology also high instep high arch talipes cavus cavoid foot and supinated foot type) is a human foot type in which the sole of the foot is distinctly hollow when bearing weight. That is there is a fixed plantar flexion of the foot. A high arch is the opposite of a flat foot and somewhat less common.
