When winter weather turns serious, the Merrell Coldpack 3 Thermo Mid Winter Boot delivers the traction, warmth, and protection you need to keep exploring. Built with Vibram Arctic Grip technology, these waterproof hiking boots grip confidently on icy trails and wet surfaces where ordinary boots slip and slide. The 200-gram synthetic insulation and fleece lining create a warm cocoon for your feet, while the advanced Solarcore Aerogel insole adds an extra layer of thermal protection without the bulk. Whether you're tackling snowy hiking trails, navigating slushy city streets, or working outdoors in cold conditions, this mid-height boot combines Merrell's proven comfort technology with serious winter performance. The waterproof membrane keeps your feet dry while still breathing, so you can push through longer adventures without the swamp-foot that ruins cold weather outings.
