We're here to help with determining the correct size and model of Renegade hoof boot for your horse. Please use our Hoof Boot Sizing Request form to send hoof photos to us, taken within a few days of a fresh trim. Please ensure the entire hoof and the end of the tape measure is shown so we can view the edges of the hooves. Side views can help show the toe angle, heel elevation and the size of the mustang roll (radius at toe). A front view can also help show any flaring and the mustang roll on the sides, or any hoof form deviations that may impact hoof boot fit.
