Scoot Boot Slim size 6 Slim converted to Scoot Boot Classic (Regular)

Sizing across brands only works through the millimetre band, never the number. Scoot Boot Slim and Scoot Boot Classic (Regular) both publish in millimetres, so a Scoot Boot Slim 6 Slim (hoof length 135 to 140 mm) is matched by finding the Scoot Boot Classic (Regular) 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.

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.
