Jacks Whirlpool Boots, perfected over 50 years, are extremely effective and therapeutic, featuring an industrial compressor that produces aeration around the cornet to massage, reduce swelling, and aid in injury recovery. The quiet motor keeps even high-strung horses calm, and the handmade soft vinyl boots are durable yet gentle on the leg. With adjustable water depth and temperature, and the option to add water-soluble medication, these compact boots offer full 360-degree aeration and can be rolled up for easy storage, fitting into a tack trunk with room to spare, all for a cost lower than most tub-type units.The boots are 24-1/2" tall with a 9" foot area (front to back) and 6-1/4" (side to side).
