Abstract
Abstract The present invention is an improved horseshoe intended for use in competitive situations. It is specifically designed to conform to the anatomical structure of the horse's hoof, and to have little effect on the performance of the horse, either due to wear of the shoe or growth of the horse. It includes: a toe sloping upwardly at the laterally extended intersection of the lower surface of the shoe and a plane, containing the axis of articulation of the hoof and extending downwardly and forwardly to the intersection; a wear-resistant area, located at the intersection, by means of a wear-resistant insert or material applied thereto; a perpendicular web at the rear of the toe portion for added support; a wedge shape to the mid-sections of the arms to improve withdrawal from turf, etc.; rounded outer edges of the heel ends of the arms, widened arms, and a relieved inner surface of the toe portion, to give greater cushioning during strenuous activities, such as running, jumping, and the like.
