Featuring three uniquely designed, reusable Arctic Flex gel packs, the cold ankle brace provides hot or cold therapy for pain-relieving support. Quickly heated in a microwave or cooled in a freezer, the removable gel packs remain flexible to contour to the arch and ankle for targeted pain relief from ankle sprains, plantar fasciitis, overuse, arthritis, tendonitis, and more. Made with a soft neoprene blend, the cold ankle brace is adjustable to securely fit most adults.
