Evo Boot size 1 converted to Flex Boot (Regular)

Sizing across brands only works through the millimetre band, never the number. Evo Boot and Flex Boot (Regular) both publish in millimetres, so a Evo Boot 1 (hoof length 124 to 129 mm) is matched by finding the Flex Boot (Regular) size that covers the same length.

Evo sizes step only a few millimetres apart and the width letters (W, WW) matter more than the number. Fit width by the letter first, then confirm the small length band, or you will land a full size out.

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.
