Brave the most extreme winter conditions and never worry about your feet with 45NRTH's Wolfgar Winter Cycling Boot. They will keep your feet warm down to -25ºF and keep out the harshest of winter days and nights. Whether you're heading out on a multi-day expedition or groomed singletrack session, the removable felted wool liner boot wicks moisture away from your feet while retaining its insulating properties. On long rides, carry a spare liner to swap out for a fresh, dry pair. Precise placement of aerogel under the foot and over the toe blocks cold and wind from chilling your feet. The 2-bolt compatible Vibram outsole is custom studdable to claw into the ice when things get slick.
