FUBUKI Niseko 3.0 Boots - Men。Never worn. The Niseko 3.0 boots are incredibly warm, incredibly durable, and incredibly lightweight. The strong EVA outer shell, in combination with the soft wool blend lining, makes this boot difficult to compete with in terms of both comfort and insulation. Design-wise, the boot has been inspired by traditional, northern Japanese fishing/road worker boots. In other words, although worn all year round by some people, this boot has been built for harsh, snowy weather conditions. With every pair of Niseko 3.0 follows a 2-layered removable insole.
