Renegade Viper size 130x120 converted to Cavallo Trek

Sizing across brands only works through the millimetre band, never the number. Renegade Viper and Cavallo Trek both publish in millimetres, so a Renegade Viper 130x120 (hoof length 120 to 125 mm) is matched by finding the Cavallo Trek size that covers the same length.

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.

Cavallo sizes on length, then you pick sole width. If your width is 6 mm or more under your length, choose the Slim sole in that size; otherwise the Regular sole.
