The Jacks Whirlpool Boots Therapeutic Horse Boots simplify the process of providing hydrotherapy to your horse. The boots provide full hydrotherapy from the hoof to above the knee. An industrial compressor (sold separately) delivers massaging aeration around the cornet that helps to reduce swelling and aid in injury recovery. The compressor produces full 360-degree aeration, and you can also vary the water depth and temperature. The boots are handmade with soft vinyl so they won’t harm the leg, but they’re durable enough for plenty of use.
