Abstract:
A shoe for a dynamic human foot comprising a sole piece having a front section where a user's fore foot would be located, a middle section and a rear section where the user's heel would be located, said rear section has a front end and a middle end and a back end, said front end is connected to said middle section of said sole piece, said sole piece having a ground engaging bottom surface and an upper surface on which the user's foot is received and, an upper piece secured to said sole piece, said upper piece providing an embracing foot enclosure enclosing the user's toes, and said bottom surface of said sole piece is rounded at said back end of said rear section at the sole piece and elevated at the rear section of said sole piece and when said shoe is resting on a flat surface, said upper surface of the sole piece where the foot would rest would not be parallel to the flat surface and would have said rear section slightly higher in elevation than said front section of said sole piece so that when the user inserts the user's foot the toes of the user's foot face towards the flat surface and are not parallel with the flat surface, said bottom surface of said sole piece having a continuous curved surface from said rear section to said front section, said bottom surface of said sole piece has a single low axis transverse the sole at said rear section located on the continuous curved surface forwardly of said back end of said rear section of said sole piece when said bottom surface is on the flat surface upon initial contact with the flat surface to assure elevation of the heel when said single low axis of said bottom surface is in contact with the flat surface so that the entire remaining bottom surface forwardly of the single low axis transverse the sole would be tilted upwardly from said rear section to said front section, whereby when said shoe is worn by a user said sole piece at said rear section at the back end of said rounded sole piece makes initial contact with a flat surface, said initial contact being at a contact axis at the rear end of said sole piece and the contact axis of said sole piece rolls in a smooth continuous motion from said rear section rolling to said middle section rolling to said front section along said continuous curved bottom surface thereby creating energy conversion means to reduce the reactive impact force, and when said shoe can be resting on a flat surface, the front end of said shoe is elevated such that said upper surface of said sole piece is parallel to said flat surface while keeping the rear section of said shoe on said flat surface.
