Back on Track® Royal Work Boots safeguard the cannon bone, tendons, and soft tissue along with providing soothing, pain relieving FAR infrared therapy. The Boots have a breathable neoprene inner layer that conforms to the leg, allowing excess heat and moisture to escape, keeping the horse fresh, relaxed, and performing at its best. For maximum comfort and protection, the Royal Work Boots combine a molded, hardwearing, nylon laminated TPU outer casing, incorporating additional reinforcement at the bottom with a thick, soft neoprene inner (perforated for extra ventilation/air flow) and lined with the revolutionary Welltex® ceramic infused fabric. A lightweight design makes the durable Royal Work Boots easy to apply and the tough elastic straps and brass buckles ensure a secure, comfortable fit.
