45NRTH Wolfgar Cycling Boot - Black/Blue Size 37. Step into Wølfgar the world's most advanced winter cycling boot. We've combined decades of winter cycling experience with NASA-grade insulation materials for a boot that keeps feet warm and dry down to -25ºF. Our 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.
