Step into the 2023 45NRTH Wølfgar Boot, the world's most advanced winter cycling boot. 45NRTH has combined decades of winter cycling experience with NASA-grade insulation materials for a boot that keeps feet warm and dry down to -25ºF. The lightweight three-piece proprietary bottom assembly is compatible with both flat pedals and 2-bolt cleats, and features a rubber outsole with microglass lugs for traction on ice. Waterproof materials and construction keep the elements out, while aerogel under the foot and over the toe block frigid air. On the inside, Wølfgar's reflective thermal lining retains warmth, and a removable wool and faux-fur liner wicks moisture and insulates. Wølfgar is a boot worthy of singletrack sessions or multi-day expeditions in the harshest winter weather.
