The Heated Liner Thermic System is a heating device within the liner system with three different heating settings for all day comfort and warmth even on the coldest days. Dial in your riding style with the Flex Adjustment which allows you to stiffen the boot or ease the flex for a custom ride. Sensor Blade Shell Technology keeps the boot lightweight by getting rid excess shell material while reinforcing key areas.
