A boot includes a rigid outer shell including a base portion adjacent to a portion of a foot of a subject, a leg portion adjacent to a portion of a leg of the subject, and an ankle support portion integral with and coupling the base portion of the main body with the leg portion of the main body, the ankle portion of the main body being adjacent to two opposing sides of an ankle of the subject, the ankle support portion of the main body having one or more removable elements. A first one of the one or more removable elements, adjacent to a first one of the two opposing sides of the ankle, is configured to be removed from the rigid outer shell to aid in preventing contact between an incision area on the first side of the ankle of the subject and the rigid outer shell.
