The Coldspark Ultra-Dry 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, without the bulk of traditional cold weather footwear. The Coldspark UltraDry uses a Retain reflective barrier to lock 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 compounds confidently grip in freezing temps. Lace-up and get after it all winter long.
