Our vision for the Wölvhammer transcended traditional cycling footwear and originated from the conceptual standpoint of a mountaineering boot. This inspiration remains in the newly redesigned Wölvhammer pulling functional elements from the original while adding style and simplicity. For 2016, we've removed the outer zipper and velcro in favor of a lace-up design with a gusseted tongue to keep wet winter weather out and warmth in. The full grain leather and ballistic nylon shell provides a durable barrier while the waterproof membrane protects your feet from the elements. Aerogel in the footbed blocks cold cleats for chilling your toes. When the snow gets deep, pair them with Bergraven Gaiters with the dedicated hook in the toe-box.
With its nano-sized air pockets that block cold and heat, aerogel is an ultra-thin, compression-resistant and waterproof insulator with the lowest thermal conductivity of any solid. It is the same insulation NASA uses to protect astronauts and sensitive equipment on missions to outer space. Created by extracting the liquid from silica gel, aerogel produces a strong, durable and flexible material that is up to five times more effective than traditional thermal insulation. Other insulation materials require loft to insulate. Aerogel does not need loft to deliver its high insulation value, making it an ideal insulator between cold metal cleats and the bottom of your feet.
An ultra-thin sheet of microporous material behind our textile shells keeps you dry and warm in the harshest weather conditions. Liquid water molecules from outside of the garment are larger than vapor molecules created by body heat from the inside. The microscopic pores are smaller than liquid water molecules, but larger than vapor molecules. As a result, waterproof-breathable membranes stop liquid from the outside, but release vapor from the inside for thermal and moisture regulation.
