Product details:

The Vasque Coldspark UltraDry Boot delivers waterproof warmth and winter traction without the bulk that's commonly found in traditional cold weather boots. This is made possible thanks to its UltraDry Waterproofing System that keeps your feet dry through snow and slush while the Retain reflective barrier locks in warmth eliminating the need for traditional insulation. Additionally, the boot's high-friction ColdHold rubber soles deliver confident grip when you're out in freezing temperatures on slick winter surfaces.
