Lots of winter boots are warm, but the Mountain 600 can go toe-to-toe with your bedroom slippers in terms of comfort. “I have sensitive feet and thought for sure I’d at least get a hot spot on steep climbs, but it never happened,” said one Colorado tester after an initial foray up 14,042-foot Mt. Lindsey. The plushness comes courtesy of a fleece lining, which never got too clammy. Rubber in the EVA midsole adds durability, making for a cushy ride that will last over hard miles.
Thanks to the Vibram Megagrip outsole—sticky rubber and diamond-shaped lugs—our tester easily scrambled up Colorado’s Tour de Abyss, a 5-mile, mud- and scree-filled hike with 3,000 feet of elevation gain. A mid-foot nylon shank supports packs up to 30 pounds, but isn’t so beefy that it inhibits a natural gait (the supple leather upper helps, too). And a waterproof membrane kept our feet dry when we were bashing through snowfields in Iceland’s West Fjords.
“The 200 grams of PrimaLoft Gold kept my feet comfy in between barefoot creek crossings in Iceland in 20°F temps,” one tester says. “I warmed up within minutes after putting these boots on again.”
