Inspired by snowboarders, the Lifty has an adrenaline-injected design that's part hiker, part snow boot. The Gore-Tex® breathable membrane and 400-gram Primaloft® insulation shut out water and the cold whether you're slope-side or making the trek to work. Waterproof synthetic and nylon fabric upper features a Dri-Lex® fleece lining in the collar and tongue. Anti-microbial footbed and TNF® Winter Grip rubber outsole. Imported. Fit best with midweight socks.
