For the most aggressive mountain riders, the second-generation Adrenaline Pro S GTX BOA® Boot continues KLIM's successful Adrenaline Boot lineup with a complete ground-up redesign.

The most popular boot in snowmobiling is now more supportive with stronger dual-zone BOA dials, designed to pop off and reattach rather than break off, combined with a molded tongue for improved closure force and lace force distribution for better ankle support. Through multi-year testing and validation to find the correct combination of durability and traction, the new Michelin® outsole, engineered specifically for powersports and custom-developed with a proprietary sole pattern, provides heavy-duty grip and durability for traction in the winter.
