The Water-Boot helps naturally with dry and brittle hooves or the risk of dry hooves. The patented hoof bell is immersed in water. The porous felt inner compartments quickly absorb a large amount of water, which is then slowly released to the hoof. To provide sufficient moisture to the hoof, a daily application of 20 to 30 minutes in the stable or paddock is sufficient. The Water-Boot in universal size is easily placed around the horse's hoof with a securely adhering Velcro fastener, just like a bell boot.
