The Classic Equine Legacy System Boot is made of 100% virgin perforated neoprene that allows the leg to breathe and heat to escape so your horse's legs stay cooler. This boot features a round cut box stitched hook-and-loop attachment with an aggressive closure making the Legacy more secure. The shock absorbing splint pad gives maximum protection to the splint bone, tendons, and other soft tissues. This boot has a refined splint pad that guards against crossfire injuries and allows for a closer, cleaner fit. A suspensory rib is positioned between the tendon and the cannon bone to ensure proper boot alignment. The Legacy boot also features a patented Cradle Fetlock System provides maximum support and protection to the lower limb by a double layer of shock absorbing neoprene. An extended layer of tough, bulletproof material fitted on the cup area ensures durability and a series of fitting darts provides for a clean, close fit. This boot has bound edges to keep dirt and debris out.
