Magnetic Hock Boots. The hock boot is designed to hold 16 neodymium magnets that develop a power of 2400 gauss each. Magnets are positioned specifically to distribute energy at the hock. Made with a breathable "Aerox" material, lined and trimmed in lycra, it guarantees the optimum temperature of the leg, thereby reducing over heating of the tendon system. These boots reduces pain and swelling, stimulates the flow of blood, speeds up the elimination of toxins and the regenerative processes. Perfect to use after strenuous exercise.
