Flex Boot (Regular) size 95 converted to Renegade Viper

Sizing across brands only works through the millimetre band, never the number. Flex Boot (Regular) and Renegade Viper both publish in millimetres, so a Flex Boot (Regular) 95 (hoof length 100 to 110 mm) is matched by finding the Renegade Viper 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.

Renegade wants 5 to 10 mm of clearance between the hoof and the boot. Do not buy the boot that equals your hoof; buy the next length or width band up within that window.
