Abstract: An improved sole for a cast shoe is disclosed herein, which sole includes three regions designed to combine together to form a sole enabling the user of the shoe thereof to walk with a more natural gait than is possible through the use of prior art designs. The three regions of the sole consist of an anterior portion, a weight bearing portion and a posterior portion. The posterior portion is radiused to facilitate the transition from heel strike to the stance phase of the gait. The weight bearing portion is substantially flat while the anterior portion is curved in both the anteroposterior radius and the mediolateral radius.
