Whether we are hiking or just adventuring around town, the Columbia Fairbanks Omni-Heat Boot is one of our top choices for winter weather comfort. It features a durable Cordua upper and Omni-TECH waterproof technology to handle rough conditions. The 200 grams of synthetic insulation combined with Omni-Heat reflective lining ensures our feet stay toasty in the coldest conditions, and the TECHLIT midsole cushions our feet every step of the way.
