Claims24
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
- a plurality of rails coupled to the lower side of the body operable to engage a surface for grinding.
A footwear for ginding, comprising:
- a sole having a forefoot portion, an arch portion and a heel portion;
- and
- a grind rail apparatus coupled to the arch portion of the footwear, the grind rail apparatus having:
- a body having a substantially flat upper side, a lower side, a first and second lateral sides,
- a plurality of rails coupled to the lower side of the body.
A method of transitioning from a stationary state to a rolling state and further to a grinding state, comprising:
- contacting at least a portion of a forefoot of a footwear on a surface, a sole of the footwear having a heel portion with an opening formed in a bottom surface of the heel portion of the sole;
- elevating the forefoot portion of the sole of the footwear relative to the surface such that either none or an insubstantial portion of a user's weight is supported by the forefoot;
- rolling on the surface using at least one wheel operable to rotate in the opening formed in the bottom surface of the heel portion of the sole of the footwear while supporting at least a portion of the user's weight;
- and
- grinding on a grind rail apparatus having a body provided with a flat upper side coupled to an arch portion of the sole of the footwear, the body further provided with at least one grind rail coupled to a lower side of the body such that the at least one grind rail grinds on a grinding surface.
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.
