Claw foot. A man's foot with pes cavus (claw foot), showing an exaggerated arch and turning up of the toes. This disorder may be present from birth or may result from damage to the nerve or blood supply to the muscles of the foot. The condition can be helped by using a moulded insole in the shoe to redistribute body weight evenly over the foot. Occasionally, surgical cutting of a tendon on the underside of the foot may be performed in an attempt to flatten the foot out.
