Abstract

Claims (21)

1. A grind rail apparatus for use on a footwear for grinding, the grind rail apparatus comprising:

a body having a substantially flat upper side, a lower side, a front, a back, a first lateral side disposed in a substantially perpendicular relationship with the upper side, a second lateral side disposed in a substantially perpendicular relationship with the substantially flat upper side, the upper side of the body configured for coupling to an underside of the footwear adjacent an arch portion of the footwear and the lower side of the body substantially arcuate between the front and the back of the body, and wherein the body is further provided with a first angled portion and a second angled portion, the first angled portion angularly extending from the first lateral side to the lower side of the body and the second angled portion angularly extending from the second lateral side to the lower side of the body; and

a plurality of rails coupled to the lower side of the body operable to engage a surface for grinding.

2. The grind rail apparatus of claim 1 , wherein the plurality of rails extend substantially longitudinally on the lower side of the body.

3. The grind rail apparatus of claim 1 , wherein the plurality of rails are further defined as having an upper side, a lower side, and a first and second lateral sides such that the upper side of the plurality of rails are coupled to the lower side of the body.

4. The grind rail apparatus of claim 3 , wherein the plurality of rails are further defined as substantially rounded about the lower side of the plurality of rails.

5. The grind rail apparatus of claim 3 , wherein the plurality of rails are further defined as substantially flat about the lower side of the plurality of rails.

6. The grind rail apparatus of claim 3 , wherein the plurality of rails are further defined as angularly configured about the lower side of the plurality of rails.

7. The grind rail apparatus of claim 1 , wherein the flat upper side, the lower side, and the first and second lateral sides of the body define a chamber within the body for retaining a shock absorbing material for cushioning the impact of grinding on a surface.

8. A grind rail apparatus coupled to a footwear for grinding, the grind rail apparatus comprising:

a first member having a substantially flat upper side coupleable to a lower side of the footwear, a lower side provided for grinding, a first lateral side disposed in a substantially perpendicular relationship with the upper side, the first member sized to extend a distance from the lower side of the footwear; and

a second member having a substantially flat upper side coupleable to the lower side of the footwear adjacent the first member, the first member sized such that when the lower side of first member engages a surface for grinding the second member extends a distance above the surface, and

wherein the first member is further provided with a first angled lateral side extending from the lower side of the first member to the first lateral side of the first member.

9. The grind rail apparatus of claim 8 , further comprising:

a third member having a substantially flat upper side coupleable to a lower side of the footwear adjacent the second member, a lower side provided for grinding, a first lateral side disposed in a substantially perpendicular relationship with the upper side, the third member sized to extend a distance from the lower side of the footwear.

10. The grind rail apparatus of claim 9 , wherein the third member is further provided with a first angled lateral side angularly extending from the lower side of the third member to the first lateral side of the third member.

11. The grind rail apparatus of claim 8 , wherein the first and second members are provided with a front coupleable adjacent a forefoot portion of the lower side of the footwear and a back coupleable adjacent a heel portion of the lower side of the footwear, and wherein the first member is further defined as substantially arcuate between the front and back of the first member and the second member is further defined as substantially arcuate between the front and back of the second member.

12. A grind rail apparatus coupled to a footwear for grinding, the grind rail apparatus comprising:

a first member having a substantially flat upper side coupleable to a lower side of the footwear, a lower side provided for grinding, a first lateral side disposed in a substantially perpendicular relationship with the upper side, the first member sized to extend a distance from the lower side of the footwear;

a second member having a substantially flat upper side coupleable to the lower side of the footwear adjacent the first member, the first member sized such that when the lower side of first member engages a surface for grinding the second member extends a distance above the surface; and

a third member having a substantially flat upper side coupleable to a lower side of the footwear adjacent the second member, a lower side provided for grinding, a first lateral side disposed in a substantially perpendicular relationship with the upper side, the third member sized to extend a distance from the lower side of the footwear, and wherein the third member is further provided with a first angled lateral side angularly extending from the lower side of the third member to the first lateral side of the third member.
