Using the latest technology from the food and pharmaceutical industries, Cool Cold Boots are designed for a daily maintenance program. More convenient than ice, these boots can be used while grooming or as part of an overall conditioning program. The entire boot is designed to be placed in a freezer or remove the individual cell packs. Take them to the horse show in a cooler bag keeping the juice and soft drinks cold and the boots frozen and ready to use. Use over the actual hoof or the pastern area. Black. One Size.
