Flex Boot (Regular) size 130 converted to Scoot Boot Classic (Regular)

Sizing across brands only works through the millimetre band, never the number. Flex Boot (Regular) and Scoot Boot Classic (Regular) both publish in millimetres, so a Flex Boot (Regular) 130 (hoof length 130 to 140 mm) is matched by finding the Scoot Boot Classic (Regular) size that covers the same length.

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.

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.
