Cavallo's easy-entry all-round boot whose width equals its length at every size, so it is cut for a round hoof. It shares the Trek length bands but pairs each length with an equal width, rather than offering a separate slim sole.
Width is measured across the widest point of the hoof on the ground surface. Length is measured from the toe to the buttress line at the back of the heel, not including the heel bulbs. Measure within two weeks of a fresh trim.
The Simple is a square boot, width equal to length. If your hoof is clearly longer than wide, the Sport (narrower) or the Trek Slim sole fits better than the Simple.
