The Air Fetlock Boot is a small, ultralight boot that goes around the entire fetlock but with an open front. The single Velcro strap is very easy to handle. This fetlock boot offers outstanding lightweight protection with Proteck Impact Gel* within the boot’s strike zone. Anatomically shaped to offer a comfortable and stable fit, the bonded shell is made of an extremely light yet strong TPU, which helps to protect against impact without compromising on style. The fetlock boot also features ventilation holes and perforated neoprene lining to prevent the legs from overheating.
