Scoot Boot Classic (Regular) size 00 converted to Cavallo Trek

Sizing across brands only works through the millimetre band, never the number. Scoot Boot Classic (Regular) and Cavallo Trek both publish in millimetres, so a Scoot Boot Classic (Regular) 00 (hoof length 100 to 105 mm) is matched by finding the Cavallo Trek size that covers the same length.

Scoot's own rule: if the hoof is 10 mm or more wider than it is long, size on the maximum width band, not the length. A round hoof can also take a Slim as a half size.

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.
