Claim 1
Independent Claim
212 words
A plastic shoe for being worn on a human foot comprising: a transparent plastic sole having a lower surface and an upper surface for fitting against the sole of a human foot, said upper and lower surfaces being visible from above and below said sole due to its transparency, and said sole having a heel area for being disposed adjacent the heel of the foot and a ball area for being disposed adjacent the ball of the foot; an upper for securing the transparent sole to the foot; and at least one opaque scuff pad disposed on the lower surface of said transparent sole at least in said ball area of said sole, said pad being visible from above the shoe through the upper surface of the sole, said pad being positioned in an area of said sole typically subject to a high degree of scuffing so that said scuff pad receives scuffing in said area instead of the lower surface of the sole, which scuffing is not visible from above the sole due to the opaqueness of the pad, and being dimensioned to extend over only a portion of said lower surface so that a substantial portion of said lower surface remains uncovered and is, therefore, visible from above said sole.
