Scoot Boot Slim size 3 Slim converted to Cavallo Trek

Sizing across brands only works through the millimetre band, never the number. Scoot Boot Slim and Cavallo Trek both publish in millimetres, so a Scoot Boot Slim 3 Slim (hoof length 120 to 125 mm) is matched by finding the Cavallo Trek size that covers the same length.

A Slim is for a hoof that measures narrower than it is long. If your width is at or above the length band, you want a Regular, not a Slim, in the same number.

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.
