Abstract
The horseshoe includes a traction surface having a toe portion defining a pair of parallel calks and a pair of side portions defining a plurality of inner and outer calks. The calks have a truncated wedge shape designed to increase traction and minimize the build-up of dirt and mud. The horseshoe is also provided with an outer coating of non-stick material which prevents mud and dirt from adhering to the horseshoe to maintain a "clean" traction surface.
