Abstract: A sole or plantar surface for footwear which may be incorporated in a walking appliance or attachment for conventional ski boots, and wherein the footwear has been deliberately configured to retain a foot in a substantially rigid and inflexible manner which interferes with a normal walking gait. The surface configuration facilitates walking by including at least one roll point area spaced rearwardly from the forward end. The one roll point area lies in a plane angularly disposed relative to the longitudinal axis of the plantar surface and in a direction towards the medial surface of the footwear.
