Light-weight plastic horseshoes (10) are held to the bottoms (12) of horse's hooves (14) by gluing them thereto, and by additionally providing preformed spaced depressions (20) in the hoof (14), into which extend fasteners (18) secured to the shoe (10); preferably the distal portions of the fasteners (18) fit tightly into the depressions (20) and are glued to the walls of the depressions (20) in one form the fasteners (18) are dowels, separate from or integral with the shoe (10); in other cases they may be expansion bolts (50), with each bolt screwed into an internally-threaded split socket (52) located in a preformed depression in the hoof (14). In other cases, dowels may be formed in situ by pouring an initially liquid but hardenable plastic through holes (72) in the shoe (70) into the preformed depressions (74) in the hoof (14), the liquid thereafter hardening to form the dowel extending through the shoe (70) and into the depression (74). |
