Abstract: A rubber material is molded into an enclosure of ungulate shape for engaging about and under a horse's hoof. The upper perimeter of the enclosure defines a rim, there being provided a generally horizontally forwardly extending lip across the rear portion of this rim. A flexible belt of textile material is arranged to pass through appropriate openings about the exterior of the enclosure immediately below the rim, the forward end portions of the belt being drawn together by a buckle to circumferentially contract the enclosure about the horse's hoof. The rear horizontally extending lip engages over the heel of the hoof to assure that the enclosure will stay in position.
