Equine Fusion Active Jogging Shoe size 8 converted to Flex Boot (Regular)

Sizing across brands only works through the millimetre band, never the number. Equine Fusion Active Jogging Shoe and Flex Boot (Regular) both publish in millimetres, so a Equine Fusion Active Jogging Shoe 8 (hoof length 76 to 85 mm) is matched by finding the Flex Boot (Regular) size that covers the same length.

Fusion sizes on length in centimetres, so a 118 mm hoof is a size 12, not 11. The width figure is a maximum, not a band, so a narrow hoof in the right length is fine.

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.
