The Merrell Moab Speed 2 Thermo Mid WP Boot allows us to keep our hiking obsession going year-round, providing warm, waterproof protection on cold, snowy trails. The boots adapt Merrell's popular Moab design with a waterproof suede and nylon upper and cozy Primaloft Gold Eco synthetic insulation keeping our feet warm in bone-chilling temperatures. The insole utilizes innovative SOLARCORE technology to provide warmth beneath our feet, so we can trudge through drifting banks of snow without feeling the icy effects. The all-purpose Vibram Icetrek outsoles ensure stable, solid footing on slick streets and trails, and the FloatPro Foam midsole cushions our step on rugged terrain.
