Why this pair
Why the Ice Boulder?
The Ice Boulder is a NexGrip men's winter boot with retractable ice cleats for icy sidewalks, a waterproof 600D nylon upper and warmth rated by NexGrip to −4°F / −20°C (100 g) or −31°F / −35°C (200 g).
Inside, Thinsulate insulation (100 g or 200 g, by version) and a 50% merino wool / 50% polyester lining hold heat without adding bulk. Available in regular and wide (4E) fits.
Choose the Ice Boulder if your winter means icy sidewalks, parking lots and packed trails. Flip the cleats down on ice and back up indoors so they don't mark floors.

Care
Follow the maker's care instructions for your exact model. Let wet boots dry at room temperature, away from direct heat. Brush off salt and dirt after use. For leather, suede and textiles, a protector spray adds a layer of water protection.
Questions about the Ice Boulder
How cold can I wear the Ice Boulder? NexGrip rates the Ice Boulder to −4°F / −20°C (100 g version) or −31°F / −35°C (200 g version). That is a lab rating; with normal socks and some walking most people are comfortable well into that range, standing still for long periods feels colder.
Is the Ice Boulder waterproof? Yes. The Ice Boulder has waterproof construction with a 600D nylon upper, so slush and wet snow stay out.
How do the ice cleats work? A set of cleats in the heel flips down for ice and folds back into the sole for indoors. They are replaceable, and replacement sets are sold on this site.
Should I size up? NexGrip boots come in whole US sizes only. If you usually wear a half size, choose the next size up. If you plan on thick socks, the same advice applies.
