First Look: Vasque Lost 40 Boot

The traditional mukluk-style boot wraps the foot and lower leg. Its flexible upper cinches tight around the calf, laces crisscrossing on leather from the ankle before wrapping up high.

This winter, Vasque adds to the genre with its Lost 40 winter boot. A hybrid mukluk, the boots have a Vibram sole and modern add-ons like softshell synthetic material and aerogel insulation in the midsole sandwiched with EVA foam.

I tromped in them for a month for this review. Temps ranged from below-zero to a slushy, 35-degree day. Overall, I like the boot, though with a few significant caveats around performance and fit.
