Our Knee Boots are ideal for prevention or recovery of injury in the tough-to-wrap knee area. Consisting of a neoprene exterior, the interior of the boot is infused 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 response. Contoured to the shape of the knee, the boot fastens with straps allowing you to easily adjust the fit. When using these boots, it helps to use standing wraps to prevent them from sliding down. https://botcanada.com/ Sizing charts can be found https://botcanada.com/sizing-charts/
