Professional's Choice Ice Bell Boot is an easy way to apply cold therapy to the feet! Interior gel pockets stay pliable even when frozen, while the nylon lining keeps skin from being directly exposed to ice. The neoprene exterior provides durability and effectively insulates the gel pockets to keep the wrap cold loner. The double hook and loop closure keeps the bell boot securely in place. To use: place the bell boots in freezer until gel packs are successfully frozen. Wet both the hoof and wrap before applying to maximize cold therapy. Leave on for recommended 20 minutes of duration and apply only under direct supervision of the horse. 30-Day Money-Back Guarantee/Six-Month warranty or as required by law. Sold in pairs.
