Abstract: The present invention provides a preformed, light weight, drop foot brace that lifts a foot by exerting a forward force on the heel to pivot the foot upwards about the ankle so that the foot won't drop during walking. The brace is also constructed so as to be light weight, easy to put on and remove and can be comfortably worn inside a shoe or without a show and still provide good lateral support by not covering the underside contact points of the foot. The brace has a shell that generally conforms to the posterior calf and is made of a resilient material that can be curved to provide the means to urge the back of the heel forward.
