• the at least one of said anterior portion and said posterior portion comprising a visible outsole map having a plurality of parallel longitudinal lines;
• said at least one protuberance being slidingly and rotatably mounted on said outsole such that the at least one protuberance can be moved to a variety of positions with respect to the visible outsole map and to contact a ground at a protuberance vertex;
• wherein said at least one protuberance comprises:
• (i) a protuberance pivot providing a rotation axis for the at least one protuberance, said rotation axis having an offset position with respect to the protuberance vertex;
• and (ii) a set of pointers positioned along a circumference of the at least one protuberance;
