The Merrell Thermo Adventure Ice+ 6in Waterproof Boot is the footwear that's ready to work as hard as you do. This boot features an M Select Dry membrane to seal out moisture yet allow your foot to breathe while you shovel the driveway and a leather outer that flexes as you move. M Select Warm insulation traps in heat to keep your foot warm even if it gets damp, and a Polar fleece lining adds extra warmth. Underfoot, a Kinetic Fit footbed provides support and cushion while the Vibram Arctic Grip outsole adds traction on wet or icy surfaces.
