The Magnetic Hock Boots allows for the most complete and even application of the BIOflex® Bio-magnetic therapy to the hock available.  The primary uses for the Hock Boot  are spavins, curbs, thoroughpins, capped hocks, arthritis and pre-warm up.  It should be remembered that magnetic therapy may be used around all the joints with no harmful effects.  Never use the magnets during the acute phase of the injury. Never use oils or medications with the magnets. However, the use of Sore No More is highly recommended. All boots Velcro™ on and are made of breathable fabric. One size fits most, except for ponies and very large draft horses.
