Sizing across brands only works through the millimetre band, never the number. Cavallo Simple Boot and Cavallo Trek both publish in millimetres, so a Cavallo Simple Boot 5 (hoof length 142 to 149 mm) is matched by finding the Cavallo Trek 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.
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.
