The Castle Pads Double Nail is a durable polyurethane hoof pad designed to provide extra protection and cushioning to the horse's sole. Its double-nail attachment design helps keep the pad securely positioned between the hoof and shoe while reducing movement. The pad absorbs shock from hard or rocky terrain, helps prevent bruising, and can be used with hoof packing materials for additional support. It is commonly used on trail, pleasure, working, and performance horses that need increased sole protection and comfort.
