Abstract
For virtually any kind of shoe, regions at the front and/or back of the heel and/or forsesole can be raised or lowered relative to the remainder of that bottom surface. In this manner, one or both of a friction or pronation adjustment can be made at the front, back, or lateral side of the foresole or heel. An adjustment device is operatively associated with one region in one of a first (foresole) or second (heel) weight bearing bottom surface, for raising and lowering the region relative to the bottom surface surrounding the region, thereby adjusting the overall texture of the weight bearing bottom surface.
