Relieve and Heal Injured Muscles, Joints, and Tendons with our Contoured Horse Knee Boots. Our Knee Boots are ideal for injury recovery or prevention in the tough to wrap knee area. Consisting of a neoprene exterior, we infused the interior of the boot with our state-of-the-art Welltex fabric, which contains ceramic powder. The ceramic reflects your horse's natural body warmth and creates a soothing far infrared thermal heat. Heat therapy is a well-recognized method used to help relieve and heal injured muscles, joints, and tendons. Contoured to the shape of the knee, the boot fastens with Velcro straps allowing you to adjust the fit. When you use these boots, it helps to use standing wraps to prevent them from sliding down.
