Footwear article with doffing ledge

Abstract:

A footwear article includes a doffing ledge that may provide a lever for pressing the footwear article in one direction, while the wearer slides his or her heel out of the footwear article in a different direction. A doffing angle of the doffing ledge is based, at least in part, on a forwardly inclined angle of a center connecting band near a rear portion of the ankle collar.
