Sizing across brands only works through the millimetre band, never the number. Cavallo Entry Level Boot (ELB) and Cavallo Simple Boot both publish in millimetres, so a Cavallo Entry Level Boot (ELB) 4 (hoof length 134 to 141 mm) is matched by finding the Cavallo Simple Boot size that covers the same length.
The ELB 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.
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.
