An equine boot attachment that allows the boot, and therefore the equine hoof, to roll forward, rearward or to the side, without unnecessary bending, thus allowing the horse to find a comfortable natural position to relieve stress on a sore, injured or diseased hoof. The rocking action of the boot attachment allows the equine to adjust its stance to find the most comfortable position, not unlike standing in a bed of sand. A “rocker” attachment and optionally a spacer, is placed on the underside of the sole an equine boot that allows the boot to rock. The attachment may comprise two components, one harder component immediately beneath the sole of the boot (and preferably patterned to mate with the contours or pattern on the underside of the sole) to which a “rocker” attachment is secured. The rocker may be adapted to have its position adjusted on the spacer. This attachment can replace expensive hoof treatment by a Ferrier and can easily be utilized directly by an equine owner.
