The Merrell Women's Thermo Chill 6in Mid Shell Waterproof Boot is your ticket to dry, warm feet, even when winter's at its worst. The durable waterproof leather upper and lightweight synthetic insulation deliver lasting moisture protection and reliable warmth, meaning you can shovel the driveway or take a long walk in fresh snow without having to quit because you can't feel your toes. A rugged rubber shell adds durability to the boot, and also protects your toes from impact with firm snow or ice. You'll appreciate the plush, supportive insole and molded arch shank after long hours playing in the snow, while the EVA midsole adds comfortable stability on uneven surfaces. To provide reliable grip on icy driveways and snowy sidewalks, Merrell finished off this winter-worthy package with a grippy, lugged sole.
