Easyboot Trail (and Trail Original / Old Mac's G2) size 12 converted to Scoot Boot Classic (Regular)

Sizing across brands only works through the millimetre band, never the number. Easyboot Trail (and Trail Original / Old Mac's G2) and Scoot Boot Classic (Regular) both publish in millimetres, so a Easyboot Trail (and Trail Original / Old Mac's G2) 12 (hoof length 170 to 180 mm) is matched by finding the Scoot Boot Classic (Regular) size that covers the same length.

The Trail's length and width bands step in 5 mm increments and overlap heavily, so several sizes can look right. Fit to width first on this rounder boot.

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.
