The stiff, dual-density EVA midsole and fiberglass insole board provide plenty of support for alpine pursuits that require crampons and kicking toe holds. Be careful of the firm insole, though: It’s extra rigid because the shoe lacks a shank, causing one tester to buy aftermarket insoles to soften up the ride.
The sticky Vibram TT Lite outsoles proved capable: “Dirt, snow, wet rock, going quick, these things stuck,” said a Colorado tester after a push up Long’s Peak. And when things get too slick for the rubber, the heel shelf makes them compatible with semi-automatic crampons.
After an entire day of hiking in ankle-deep snow, one tester labeled the Charmoz Pro as “bulletproof.” The Gore-Tex-lined upper let in zero moisture, and the nylon upper regulated the temperature perfectly. Temperatures bottomed out at 17°F during one test hike, and our tester’s feet only started to feel chilly at the end of the seven-hour trek.
The stiff sole, toe bumper, and 360-degree rand give the boot as much armor as a plastic boot.
