Wintertime requires rugged, waterproof, insulated boots. Our Chillberg men's insulated winter boots are designed to log hours outdoors in rough, cold conditions, with 400 grams of Primaloft® insulation helping to keep your feet warm and dry. There’s also a shock-absorbing EVA midsole for cushioning. Plus, they're made with eco-conscious materials – the 100% fleece lining is made entirely from recycled plastic bottles.
