Warm, stiff, and built for aggressive sled days. Dual-zone BOA lets you lock the heel and set forefoot flex separately, while the HydrX Pro membrane blocks melt and slush. Insulation is rated to -50C with a micro fur fixed liner for heat without sloppy fit. An articulated cuff, stiff reinforcements, and a molded heel insert keep the boot from folding when you drive the chassis hard. Deep FXR tread with a concave footprint grips boards and snow, with toe/heel kicks for quick clears.
