Cavallo Simple Slim Sole Hoof Boots Cavallo Simple Slim Sole Hoof Boots are simple front-fastening with industrial grade Velcro(R) closures. They are simple to put on and take off, and stay securely on-hoof. They are shaped for the natural hoof with a moulded-in back flap for bulb protection and abrasion resistance. Durably constructed with a waterproof tread, rustproof metal, and high-performance TPU outsole, they are lightweight and have built-in drainage. Healthy hooves are promoted by allowing expansion and contraction, and increased blood circulation. See measuring and sizing info at right.
