(Jacks) Over 50 years of reliability behind these effective, therapeutic boots. The quiet running industrial compressor produces aeration around the coronet that massages, reduces swelling and aids in injury recovery. The boots are vinyl, built for years of use, yet soft so they will not harm the leg. Water depth and temperatures can be varied, and medications (water-soluble) can be added. Use as pair or for individual leg treatment. Unlike tub-type hydrotherapy systems, you get full 360-degree aeration and the ability to roll up the boots. They are compact enough to fit the whole set into a tack trunk and still have room to spare. Boots can be used on front or hind legs. Includes 110-volt compressor, three piece hose set, check valve and suspender set.
