Our Equine Innovations Air Shock Jumping Fetlock Boots are designed with an innovative, shock absorbing air cushion for maximum flexor tendon impact protection and boot comfort. The anatomically shaped design is lightweight, and comfortable and sits perfectly positioned on the horse's leg providing advanced concussion and impact protection. The strike area uses dual injection molding making the area stronger while flexible to soften and spread out the impact and concussion. The airbag lays flat in the strike guard space between the inner foam lining and the outer strike guard.
