1. A cushioned horseshoe for a racehorse comprising:

a generally "U" shaped metal horseshoe plate;

having a generally rectangular cross section of substantially uniform thickness;

having a hoof engaging surface and a tread bearing surface;

having a plurality of conventional nail holes extending through said plate and spaced longitudinally therealong, the last nail hole on each arm of said "U" shaped plate being spaced from the free ends thereof;

a heel portion extending from the last of said nail holes on each arm of said "U" shaped plate longitudinally therealong to the free ends thereof;

having one or more heel cushion holes through each heel portion of said plate from said hoof engaging surface to said tread bearing surface;

a unitary resilient tread bonded to substantially the entire tread bearing surface of said plate and molded to include:

a base portion of uniform thickness bonded directly to the tread bearing surface of said plate and extending substantially thereacross;

a toe calk raised above said base portion;

a heel calk raised above said base portion on each heel portion thereof, said base including in each said heel portion projections extending through said heel cushion holes in said plate and adapted to resiliently engage the horse's hoof to provide a substantial thickness of resilient cushioning material for the horse's heel equal to the combined thickness of said projection, said base and said heel calk; and,

a plurality of traction cleats raised above said base and distributed from said toe calk to said heel calks and positioned between said nail holes.

2. Cushioned horseshoe according to claim 1 wherein said plate is made of aluminum.

3. Cushioned horseshoe according to claim 1 wherein said resilient tread is made of natural rubber.

4. The horseshoe according to claim 1 further including a steel toe piece affixed to said plate and projecting a distance from said tread bearing surface greater than that of said raised toe calk.

5. The cushioned horseshoe according to claim 1 wherein the opposing side walls of the said raised tread portions slant toward each other in the direction away from said tread bearing surface to facilitate the automatic removal of dirt, mud or turf from between the tread portions while the horse is running.

6. The cushioned horseshoe according to claim 1 wherein said base includes a countersunk portion in an area about said nail holes of sufficient size to permit the head of nails that will be used to affix the horseshoe to the horse's hoof to bear against said tread bearing surface of the plate, substantially without intervening tread material.

7. The cushioned horseshoe according to claim 1 wherein said plate includes concave bevel on the inside edge of said tread bearing surface in the toe area thereof to facilitate the distribution of forces throughout the toe area.

8. The cushioned horseshoe according to claim 1 wherein said heel cushion holes are countersunk from said tread bearing surface and said hoof engaging surface to eliminate sharp metal surfaces and to permit a flange to be molded on said tread projection to help hold said tread to said plate.
