Explora Hoof Boots size 2 converted to Flex Boot (Regular)

Sizing across brands only works through the millimetre band, never the number. Explora Hoof Boots and Flex Boot (Regular) both publish in millimetres, so a Explora Hoof Boots 2 (hoof length 120 to 130 mm) is matched by finding the Flex Boot (Regular) size that covers the same length.

Do not read the plain number and the E number as one size. An Explora 2 and an E2 share a length band but the E2 is the narrower boot; pick the line by your measured width.

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.
