Cabin fever has a new cure and it’s called Coldspark UltraDry™. Whether your winter therapy is a hike to a frozen mountain lake or a trek to the mailbox, Vasque’s new Coldspark provides the extra dose of confidence to tackle any winter outdoor adventure. We have 200g 3M™ Thinsulate™ insulation keeping your feet toasty without looking like you just returned from the Yukon. Our proprietary UltraDry™ protects from the elements while our ColdHold dual-compound polymer outsoles and multi-directional tread pattern provide the traction to keep pushing when the going gets slick. Warm, dry feet, tenacious traction and a modern look, why would you want to stay inside?
