These waterproof Coldspark UltraDry boots from Vasque are great for any season, but built to keep you warm and safe on slicker surfaces. They provide all the support you’ll need, whether you’re hiking up a mountain or trekking around the city. The boots are made of a breathable TPU Yarn Mesh and treated leather. Vasque uses their Retain insulation—an aluminized reflective material bonded to the lining—to reflect heat while keeping the shoe super-breathable. Their UltraDry membrane also keeps your feet from getting wet. You’ll stay warm without getting sweaty or soggy feet. The boots weigh only two pounds, so they feel more like sneakers. To protect you from slipping, the soles on the bottom have a multi-directional tread for particularly wet or icy surfaces.
