The lower or ground contact layer has a recessed groove and nail holes provided along the interior surface of bottom surface of the lower layer. The upper layer or hoof contacting layer has nail holes formed in it which are aligned with the nail holes of the lower layer such that the horseshoe can be readily attached to a hoof of a horse. The upper and lower layers are also secured at locations separate from the nail holes so as to provide a pre-assembled, multi-layer horse-shoe. ## Claims ### Claim 1 A horse-shoe, comprising: an upper layer designed for contact with a hoof of a horse, said upper layer having nail holes; a lower layer adapted for ground contact, said lower layer being U-shaped and having a recessed area which is defined by side edge walls and a substantially continuous recess bottom surface extending from one end of said U-shaped lower layer to the opposite end, said recess bottom surface having nail holes formed therein, and said horse-shoe being arranged such that nail holes in said upper and lower layers are in alignment so that horse-shoe nails are adapted to pass through said upper and lower layers when said horse-shoe is being secured to a horse; an intermediate layer sandwiched between said upper and lower layers and formed of an elastic material so as to provide an added shock-absorbing function to the horse-shoe; and securement means which is separate and distinct from said intermediate layer for securing said upper and lower layers together such that said intermediate layer is sandwiched therebetween, and said securement means providing a preassembled multi-layer horse-shoe ready for securement to a hoof of a horse. ### Claim 2 (depends on 1) A horse-shoe as recited in claim 1 wherein said upper and lower layers are of aluminum. ### Claim 3 (depends on 2) A horse-shoe as recited in claim 2 wherein said elastic layer is formed of rubber. ### Claim 4 (depends on 3) A elastic as recited in claim 3 wherein said horse-shoe is formed of silicone rubber. ### Claim 5 (depends on 2) A horse-shoe as recited in claim 2 wherein said intermediate layer and upper layer are essentially of equal thickness. ### Claim 6 (depends on 5) A horse-shoe as recited in claim 5 wherein said lower layer has a thickness greater than that of said intermediate layer. ### Claim 7 (depends on 1) A horse-shoe as recited in claim 1 wherein said elastic layer is formed of silicone rubber. ### Claim 8 (depends on 1) A horse-shoe as recited in claim 1 wherein said intermediate layer and upper layer are essentially of equal thickness. ### Claim 9 (depends on 8) A horse-shoe as recited in claim 8 wherein said lower layer has a thickness greater than that of said intermediate layer. ### Claim 10 (depends on 1) A horse-shoe as recited in claim 1 wherein said upper and lower layers include a first set of aligned nail holes that are arranged in series on a first side section of said horse-shoe and a second set of aligned nail holes that are arranged in series on a second side section of said horse-shoe. ### Claim 11 (depends on 10) A horse-shoe as recited in claim 10 wherein said securement means includes multiple securement members positioned at opposite ends of each of said first and second sets of aligned nail holes. ### Claim 12 (depends on 1) A horse-shoe as recited in claim 1 wherein said securement means includes a plurality of securement members extending from said upper layer to said lower layer. ### Claim 13 (depends on 12) A horse-shoe as recited in claim 12 wherein said securement means includes multiple securement members positioned at opposite ends of first and second sets of aligned nail holes. ### Claim 14 (depends on 1) A horse-shoe as recited in claim 1 wherein said securement means secures said upper and lower layers together so as to preclude axial displacement of said layers at a time both prior to and after nailing of said horse-shoe to a hoof of a horse. ### Claim 15 (depends on 1) A horse-shoe as recited in claim 1 wherein said upper, intermediate and lower layers all have corresponding peripheral edges over an entire periphery of said horse-shoe. ### Claim 16 (depends on 1) A horse-shoe as recited in claim 1 wherein said horse-shoe includes two side portions each with a plurality of nail holes as well as an intermediate area and said bottom surface continuously extends at a common level from a first side portion, through the intermediate portion and through the opposite side portion. ### Claim 17 A multi-layer horse-shoe, comprising: an upper layer designed for contact with a hoof of a horse, said upper layer having nail holes formed therein; a lower layer adapted for ground contact, said lower layer being U-shaped and having a recessed area which includes a substantially continuous recess bottom surface having nail holes formed therein and extending from one end of said U-shaped lower layer to the opposite end, and said horse-shoe being arranged so that nail holes in said upper and lower layers are in alignment such that horse-shoe nails are adapted to pass through said upper and lower layers when said horse-shoe is being secured to a horse; an intermediate layer sandwiched between said upper and lower layers and formed of an elastic material so as to provide an added shock-absorbing function to the horse-shoe; and securement means which is separate and distinct from said intermediate layer for securing said upper and lower layers together such that said intermediate layer is sandwiched therebetween and such that the layers are prevented from separating apart so that said horse-shoe is adapted for securement to a hoof of a horse while said multi-layer horse-shoe is in an assembled state. ### Claim 18 (depends on 17) A horse-shoe as recited in claim 17 wherein said upper, intermediate and lower layers all have corresponding peripheral edges over an entire periphery of said horse-shoe. ### Claim 19 (depends on 17) A horse-shoe as recited in claim 17 wherein said securement means includes a plurality of securement members extending from the upper to the lower layer. ### Claim 20 (depends on 17) A horse-shoe as recited in claim 17 wherein the bottom surface of the recess extends continuously across a plurality of nail holes and at one level across said nail holes.
