Warm and mobile, Sorix2 is the winter boot for active days in freezing cold. It has seen some design and functional updates for FW14 but it still sends the same message, that low temperature shouldn't stop you from spending time outside. Full lace up provides excellent fit and the thermostatic sole efficiently blocks the cold coming from the ground, while still maintaining a very low weight and being highly mobile. Waterproof BUGdri membrane and a durable leather and textile shell lined with Thinsulate and Boa pile make Sorix2 a true heavy duty winter boot, with a comfort zone down to -40C. The outsole has BUGrip 2.0 studs that are constructed to give the best overall traction on snow and ice.
