Scoot Boot Classic (Regular) size 11 converted to Flex Boot (Regular)

Sizing across brands only works through the millimetre band, never the number. Scoot Boot Classic (Regular) and Flex Boot (Regular) both publish in millimetres, so a Scoot Boot Classic (Regular) 11 (hoof length 160 to 165 mm) is matched by finding the Flex Boot (Regular) 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.

Flex fits within plus or minus 5 mm of the listed width and no longer than the listed length. A naturally round or upright hoof wants the Flex Wide, whose length and width match, rather than the Regular.
