Dorsal retraction of the toes is usually present and bears an important relation to its development, but is not a part of the cavus itself. The high point of the arch should be located at the talonavicular joint. Regardless of the etiology of the neuropathy, intrinsic muscle atrophy and imbalance among different muscles group of the leg leads to features of pes cavus including high arch, clawing of the toes, and equinus deformity.
