A post-operative shoe and method for construction thereof is provided. The post-operative shoe includes an outsole having a substantially flat top surface with variable rigidity and rounded toe and heel ends and a midfoot segment located between the toe and heel ends. The rigidity of the outsole is most rigid after a medical procedure performed on a wearer of the outsole and less rigid as time passes from the medical procedure. One or more bores are formed within the outsole, each bore originating at the toe end and terminating at one of a proximal end of the toe end and a distal end of the midfoot segment. One or more flex rods are each sized to fit within one of the bores to determine the rigidity of the outsole.
