Abstract
Abstract A therapeutic walking device has features to aid sufferers from cerebral palsy in reducing the tendency to walk on the balls of the foot. The device includes a foot section and a calf section formed at a 90 degree angle. The foot section has a heel support and a toe support for supporting the heel and toes of the user. A recessed section separates the heel support and toe support and is spaced lower so as to prevent pressure from being exerted on the sole of the foot between the heel and toes. The leg section is strapped about the calf of the user's leg.
