The Legacy 2 Fetlock Cradle System provides maximum support and protection to the fetlock and lower portion of the leg. It mimics the design of, and therefore reinforces, the ligament it is intended to support. Made of 100% virgin neoprene that provides four-way stretch for ultimate flexibility. Suspensory rib ensures proper boot alignment. Perforated body allows heat to escape and the leg to breathe. Shock-absorbing splint pad guards against crossfire and other scalping injuries. Hook-and-loop closures with elastic reinforcement provide exceptional grip and durability. Soft lycra inner layer cleans easily and dries quickly. Tough, elastic exterior fabric extends to the base of the boot to ensure a close, comfortable fit. Bound edges help keep out dirt and debris.
