Gear Review: Muck Boot Arctic Sport Winter Boots

These are the warmest (and lightest) boots you will ever need for winter.

Felt liners, like those on the Sorels, are great for temps down to about zero. But in colder climes, go for this boot, made from rubber-covered closed-cell foam. It’s less breathable, but warmer (and lighter). “And it’s virtually immune to abuse,” says a Vermont tester who’s worn her pair through five winters, in temps down to -15°F.

The EVA midsole is supportive with good rebound: On short hikes over rolling Adirondack terrain, testers pulled sleds and carried up to 35 pounds. Broad lugs provide traction for snow stomping in all but steep terrain. Fit is roomy. $120; 3 lbs.; m’s 5-15;
