Rocker shoe and attachment for an equine boot assembly
View Patent ↗An equine boot attachment and/or solid structure shoe that is designed to be attached on the underside of an equine boot or an equine hoof that allows the boot or hoof to roll forward, or to the side, without unnecessary bending, thus allowing an equine user to find a comfortable natural position to relieve stress on a sore, injured or diseased hoof. The rocking action allows the equine to adjust its stance to find the most comfortable position, not unlike standing in a bed of sand. This ability to find a naturally comfortable standing position is especially important for equine with lameness such as laminitis.
1. An equine boot assembly comprising;
a fabric boot having sides and a closed bottom disposed in a sole plate structure having an underside and side walls that define a receptacle for the bottom of the fabric boot, the sole plate structure side walls being sufficient in height to constrain lateral expansion of a deformable elastomer gel orthotic pad and in which the underside of the sole plate structure is sloped from a centerline measured front to back toward the front of the sole plate structure; and
a removable solid rocker attachment structure having no opening in a center that is attachable to the underside of the sole plate structure, the removable solid rocker attachment structure having a top side, a bottom side, edges, a front and a rear, wherein the top side is straight and the bottom side is sloped from a centerline measured front to back toward a front of the rocker attachment structure and wherein the removable solid rocker attachment structure having a top polymer section and a softer lower polymer section below the top section, the top section abutting the lower section and molded thereto;
wherein a spacer element is disposed between the solid rocker attachment structure and the underside of the sole plate structure with securing means that allow the removable solid rocker attachment structure to be moved.
2. The assembly of claim 1 wherein the solid rocker attachment structure is made of polyurethane having a Shore A hardness above about 75-85.
3. The assembly of claim 1 wherein the solid rocker attachment structure bottom side is sloped to the front from the center measured from front to back at an angle of 15 to 45° and is rounded at the rear.
4. The assembly of claim 1 wherein the solid rocker attachment structure contains polymeric fibers or powered TEFLON™.
5. The assembly of claim 1 wherein the solid rocker attachment structure and the spacer element are molded together as an integral piece.
6. The assembly of claim 1 wherein the solid rocker attachment structure and the spacer element are molded of polyurethane, and the spacer element is made of harder material than the softer lower polymer section of the solid rocker attachment structure.
7. The assembly of claim 1 further comprising the deformable elastomer gel orthotic pad disposed in the bottom of the fabric boot wherein the elastomer gel orthotic pad has a Shore A hardness of from about 20 to 70 and whereas the solid rocker attachment structure has an underside that is patterned.
8. The assembly of claim 1 wherein the underside of the sole plate structure is patterned and a top side of the spacer element is patterned in a manner to mate with the pattern of the underside of the boot.
9. The equine shoe of claim 1 wherein the top polymer section of the solid rocker attachment structure is made of a hard polymer having a width of about 5-30% total width of the solid rocker attachment structure and has a Shore A hardness of from about 85 to 100 and wherein the softer lower polymer section has a Shore A hardness of about 45-70.
