Only tried once, could not return. The Back on Track Performance Bell Boots are suitable for use during training and competition as well as around the farm. Designed to reflect the horse's own body-warmth, these boots create a soothing far infrared thermal heat, which can help alleviate pain associated with inflamed muscles, ligaments, tendons, and joints. The anatomical design ensures a perfect fit and prevents the boots from spinning. Used for both injury prevention as well as injury recovery. The Back on Track Performance Bell Boots are ideal when having problems with the tarsal bones or the coronet, as the boots increase the blood flow in the hoof. Sold in pairs.
