Mens Isotherm Zip Waterproof Boot

Protected by more waterproofing than you can shake a garden hose at (which you've dutifully disconnected for the winter season), packed with layers of high-loft insulation, and riding atop one of Vibram's most aggressive hiking soles, the Merrell Isotherm boot grabs onto deep snow and cold-slick surfaces and plunges into clear mountain streams while keeping your feet oblivious to the below-freezing trauma they're missing.

Batten down the hatches with a quick zip and head out — or jump if the snow’s piling up. The Isotherm’s attractive full-grain leather and pig suede upper naturally add a layer to the already waterproof breathable membrane to keep your feet dry. Inside the boot, antimicrobial fleece and ample Primaloft insulation wrap your feet in warmth, and the ActiveHeat insole adds extra heat when you need it, with its silver reflective film. Merrell's Air Cushioned Ortholite anatomical footbed provide support and shock-absorption for days where the trail proves a little more daring. The zip closures seal the boot up tight and eliminate possible snags and lace re-ties. And set on top of a deep, aggressive Vibram lugged sole, your warm feet will take you through the gnarliest winter terrain with confidence.
