The ideal combination of ankle articulation and rigid crampon support.

Mixed alpine routes often include a long approach by trail, scrambling over loose terrain, followed by steep sections of ice and rock. Luckily, the Lowa Men's Weisshorn GTX Mountaineering Boot was built to handle it all. The Flexfit Synchro technology allows the ankle to flex and articulate on steep trail sections while the rigid I-Core midsole and TPU stabilizer provide a rigid platform for automatic crampons. Plus, the Gore-Tex membrane and toasty Duratherm insulation will keep your foot dry and comfy in the harshest alpine conditions.

Thoroughly pleased with this boot!

    Bought these over a year ago but took the maiden voyage this weekend on MT Washington. I carried a heavy load in on well packed trails and the boots were incredibly comfortable. No break in needed. They stayed warm at camp in sub zero temps for hours. The climb was with crampons on packed trail, to extreme steeps which required an ice axe, to some straight up ice to rocky mixed terrain. These boots handled it all with so much comfort, traction and support I never really even thought about my feet. A bit pricey, but this is a serious mountaineering boot
