THE NORTH FACE Nuptse Bootie Waterproof VII Dyneema Unisex TNF Black x TNF Black Size: US8 (26.0cm) Color: Black * The upper material uses "Dyneema" for high abrasion resistance. "THERMOLITE ECOMADE" is used for insulation, and "TEKWPROOF" is used for waterproof and breathable material, protecting your feet from the cold and wet of the autumn and winter seasons. The "Vibram ARCTIC GRIP ALL TERRAIN" outsole provides a firm grip even on icy surfaces. #THENORTHFACE * I purchased these, but I have no opportunity to wear them, so I will sell them to someone who is interested.
