Claims23
Shoe apparatus for riding along an elongated support surface, comprising:
- a compressible midsole formed in the arch area with a downwardly opening cavity having a predetermined configuration and medial and lateral upturned walls;
- a rigid riding plate having medial and lateral sides and configured on its upper side to complement said predetermined configuration and being formed with a downwardly facing surface to, in use, be directed over said elongated support surface;
- said plate being formed on at least one side with an upwardly raised flange flanking the adjacent upturned wall of said midsole;
- and
- a wear resistant tab interposed between said adjacent side of said midsole and an inwardly facing surface of said flange, said tab being attached to said midsole and configured to slidingly engage said inwardly facing surface as said cushioned midsole in said arch area is compressed and released.
