Rubber Pull On Bell Boots protect your horse from pulling their shoes and overreaching. These are great in the pasture, or for cross country jumping as they will stay on better than ones with velcro closures. They are made from durable rubber with enough stretch to get over your horse's hooves. Sold as a pair. For horses with sensitive skin that have trouble with bell boots rubbing, try Second Skin Pastern Protection, designed specifically for that reason.
