The Heavenly Omni-Heat Boot features a chic design and a lightweight upper that doesn't leave us sweating when running errands. It's backed by Columbia's Omni-Tech waterproof tech and efficient Omni-Heat insulation, which uses reflective material to keep feet toasty in freezing temps. Along the outsole, a capable rubber tread gives us consistent traction on slushy sidewalks and icy driveways.
