The outside of the BR tendon boot Pro Max is made of sturdy artificial leather. The hard synthetic shell on the inside, which is shaped to the horse's leg, provides optimum protection against external influences. This prevents your horse from getting injured. The protector has a strong, shock-absorbing neoprene lining of 5mm. Neoprene is soft for the horse's leg to prevent rubbing. The moulded plastic shell fits snugly and the protector can be fixed to size with the wide Velcro fasteners. The tendon boots are suitable for the front and hind legs.
