Hit the streets and trails with confidence this winter with Viking's innovative response to the ice and cold. In this updated version, an already aggressive tread pattern on the shoe's outsole has been upgraded with rugged steel spikes that bore into icy surfaces to provide secure grip with every step. A waterproof GORE-TEX membrane and warm insulation ensures feet stay dry and comfortable in changing ground and weather conditions. In addition to providing quick fastening and the perfect fit, the Boa Fit System also contributes to an overall sleek and minimalist look that makes Rask 2 Warm Spikes Mid GTX Boa just as well suited to the daily commute as to icy forest paths.
