Equine Fusion Active Jogging Shoe size 15 converted to Scoot Boot Classic (Regular)

Sizing across brands only works through the millimetre band, never the number. Equine Fusion Active Jogging Shoe and Scoot Boot Classic (Regular) both publish in millimetres, so a Equine Fusion Active Jogging Shoe 15 (hoof length 146 to 155 mm) is matched by finding the Scoot Boot Classic (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.

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.
