Warm, dry feet make all the difference when the weather is cold and wet. Made for winter hikes, snowshoe adventures and long, cold days outdoors, these adidas Terrex winter boots are waterproof and fully insulated. COLD.RDY with PrimaLoft® wraps your foot in heat-sealing warmth, while RAIN.RDY seals out slush, snow and rain to keep feet dry all day long. A BOA® Fit System lets you dial in a precise fit for confident footing. A BOOST midsole cushions and brings energy to every step, on and off the snow and in all temperatures. The Stealth winter grip rubber provides high-friction traction for confident footing on slick, icy ground.
