Sizing across brands only works through the millimetre band, never the number. Cavallo Simple Boot and Cavallo Sport Boot both publish in millimetres, so a Cavallo Simple Boot 5 (hoof length 142 to 149 mm) is matched by finding the Cavallo Sport Boot size that covers the same length.
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.
The Sport is the narrow cut, roughly 6 mm under the Simple in width. A round hoof whose width equals its length will pinch in a Sport and wants the Simple instead.
