Winter hiking calls for boots that can stand up to the elements. We trust the Merrell Coldpack 3 Thermo Tall Zip WP Boot for its premium materials, waterproof and insulated construction, and aggressive rubber outsole. Merrell's impermeable membrane helps seal out the rain and snow, and the waterproof leather adds an extra defense against the wet, while the YKK waterproof zipper ensures water doesn't find another way in. As we trek over rough terrain, the mesh inserts let our feet breathe, Merrell's heel Air Cushion boosts shock absorption to reduce fatigue, and the Super Rebound Compound midsole propels us onward. Packed with 200 grams of synthetic insulation, this pair keeps our feet warm even if moisture does get in, while the thin, flexible SOLARCORE aerogel insole shields the soles of our feet from the chill of the frozen, snow-covered ground.
