Nexgrip's Whisky boots for men keep you in your comfort zone in sub-zero temperatures. With 100% premium leather, waterproof zipper and membrane, and 100g Thinsulate insulation, it's no wonder they're so warm and dry. The lining is a perfect 50/50 blend of Merino wool and polyester, and the removable polyurethane insole, aluminum/felt layer, and natural rubber outsole make them as comfortable as they are durable. Plus, the rust-resistant stainless steel cleats and retractable anti-slip outsole are truly next-level. All this, and it's stylish to boot!
