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) 135 (hoof length 140 to 150 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.
