Men's Ice Caleb Waterproof Insulated (100g)

A lace-up leather boot with a textile collar and dual waterproof YKK zippers for easy on and off. It's rated for comfort from -15°C to -20°C (5°F to -4°F) depending on the insole, with a gold-rated leather upper over a 100% waterproof membrane, 100g of Thinsulate insulation and a Merino wool/polyester lining, plus a removable polyurethane insole over a removable aluminum/felt layer that blocks ground cold and lets you fine-tune the fit. NexGrip's patented, rust-resistant stainless steel cleat flips down from the heel for ice and folds away when you head indoors, and the natural rubber outsole adds anti-slip grip at the forefoot. Men's sizes 6 to 13, with 4E widths available.
