When winter kicks it up a notch, Merrell Isotherm Zip waterproof winter boots kick in. Whether you work or play outside in winter, your comfort absolutely depends on your ability to stay warm and dry, starting with your feet. Isotherm 8s have you covered, with a completely waterproof shell, generous Primaloft® insulation, and a heat-reflecting insole. And they go farther, with comfort features like a compression-molded EVA footframe, air cushion in the heel, and a bellows tongue to keep debris out of the boot. For snowshoers, Merrell has added a snowshoe-strap ridge for extra stability. And for the style conscious and lacing-challenged, Merrell offers the front zip, which gives the boots a sleek profile and makes them even easier to get on and off.
