Dont get confused with club feet. Clubfoot is a birth defect where one or both feet are rotated inward and downward. The affected foot and leg may be smaller than the other. In about half of those affected, both feet are involved. Most cases are not associated with other problems. Without treatment, people walk on the sides of their feet, which causes problems with walking.
The exact cause is usually unclear. A few cases are associated with distal arthrogryposis or myelomeningocele.
