Colder days are on the way. Soon autumn leaves will be buried beneath snow & ice. And when those sub-zero days arrive, your feet will be stoked if they’re laced into Columbia’s Powderhouse Titanium Omni-Heat 3D Outdry boots. Designed for extreme cold, they feature a waterproof-breathable upper, a thermal-reflective lining, and 600g insulation to keep cold out and warmth in. They’ve also got a high-grip Michelin outsole for solid traction in all kinds of sketchy winter weather.
