These hock boots by Back on Track are the real therapeutical wonder. Designed with unique Welltex™ technology which when in contact with the skin of your horse creates infrared waves that in turn create therapeutic warmth which improves circulation and lessens tension and pain relief. These boots are great to use during the healing process or as an aid to avoiding injuries during training periods. It is recommended to wear these boots only during rest, stabling or turnout periods. These boots are protected with durable neoprene casing and are available in sizes from small to extra large. Important note: When your horse lays down the neoprene boot might stretch to such extent that stitching might rip or neoprene shell might tear – these tears are non-repairable.
