Talipes
Clubfoot.
The Latin word talipes was compounded from talus (ankle) + pes (foot) since, with the common ('classic') type of clubfoot (talipes equinovarus), the foot is turned in sharply and the person seems to be walking on their ankle.
Talipes equinovalgus: Malformation of the foot evident at birth in which the heel is elevated like a horse's hoof (equino-) and the heel is turned outward (valgus).
