Pes cavus
Pes cavus, also known as high arch, is an orthopedic condition that presents as a hollow arch underneath the foot with a pronounced high ridge at the top when weight bearing. This foot type is typically characterized with cavus—the elevation of the longitudinal plantar arch (e.g., the bottom arch of a foot), plantar flexion of the foot, forefoot pronation, hindfoot varus, or forefoot adduction.
