The Coldspark UltraDry™ is an insulated boot for hikers who don’t slow down when the temperature drops. The performance-driven boot delivers warmth, waterproofing, and winterized traction. A retain and reflective barrier locks warmth into the boot, cutting out the weight of traditional insulation. An UltraDry™ waterproof membrane keeps feet dry through slush and snow, while the outsole’s high friction ColdHold rubber compound confidently grips in freezing temps.
