Show Description

One for the Himalaya, this superlight double boot features an insulated inner boot you can use for walking around base camp. The thermo-reflective outer boot layers on warmth, and a durable Cordura gaiter with Kevlar reinforcements lets you take it to extremely cold settings. Inside, a carbon fiber insole adds support, and closed-cell foam helps fend off the cold. EVA makes the midsole cushy, and TPU inserts ensure longevity. Reliable Vibram® PE rubber gives the sole plenty of traction, and the rubber rand protects the boot from wear-and-tear so you can tackle 8,000-meter peaks weekly.
