Sizing across brands only works through the millimetre band, never the number. Cavallo Sport Boot and Cavallo Trek both publish in millimetres, so a Cavallo Sport Boot 3 (hoof length 126 to 133 mm) is matched by finding the Cavallo Trek size that covers the same length.
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.
Cavallo sizes on length, then you pick sole width. If your width is 6 mm or more under your length, choose the Slim sole in that size; otherwise the Regular sole.
