Cavallo Cute Little Boot (CLB) size M4 Slim converted to Cavallo Trek

Sizing across brands only works through the millimetre band, never the number. Cavallo Cute Little Boot (CLB) and Cavallo Trek both publish in millimetres, so a Cavallo Cute Little Boot (CLB) M4 Slim (hoof length 93 to 102 mm) is matched by finding the Cavallo Trek size that covers the same length.

The CLB tops out around a 102 mm hoof. A pony measuring past that has outgrown the CLB and belongs in a Trek 0 or an Easyboot Mini-to-small range 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.
