What to know about clubfoot. Clubfoot (also known as talipes equinovarus) is a congenital (present at birth) foot deformity. It affects the bones, muscles, tendons and blood vessels and can be present in one or both feet. In clubfoot, the heel points downward, while the front half of the foot turns inward. The calf muscles on the affected side are smaller than on the normal side; the leg on the affected side is slightly shorter than on the other side.
