The Merrell Coldpack 3 Thermo Moc Waterproof Shoe is a winter moc that's made to keep our feet warm in the chilly conditions. The leather uppers and waterproof membrane seal out snow and slush while a fleece liner and layer of synthetic insulation keep our feet warm as we slip outside to walk the dog, run to the store, or shuffle our way down slick sidewalks to hit our favorite coffee shop or wine bar. These mocs more or less live next to our front door in winter, so we can slip them on quickly and venture out into the cold for whatever our day has on tap.
