The toe area of the base shoe consists of a Locking Coupling that holds the wearing sole at the toe. The nail holes are individually angled allowing the nails to follow the slope of the hoof and give the optimum shoeing. The hard plastic material that is injected between the top surface and bottom surface provides a tight grip on the horseshoe nails. This ensures great strength when the shoe is fitted to the hoof. The heels have Locking Slots that hold the wearing sole at the heel.

The heels of the wearing soles contain metal clips imbedded in the urethane which fit into the heel clips on the base shoe. The whole locking system was designed to utilize the forces transferred to the wearing sole by the movement of the horse to increase the attachment of the wearing sole to the base plate.
