Protector Boots are made from a unique blend of 90% PVC and 10% nylon, which gives them superior softness and flexibility compared to many other boots on the market. The practical fastening with double Velcro straps makes them easy to adjust for a secure fit. These boots are designed to protect the bulbs of the horse's heel and its hooves from impact and injury, while effectively preventing the horse from pulling off its shoes. Sold in pairs.
