The Scarpa Inverno Mountaineering Boot has been a staple in our ice and alpine climbing arsenal for years and still remains the go-to choice for cold, multi-day ascents. From Alaska to the Andes to the Alps, countless climbers have trusted the bomber Pebax upper and Vibram sole to handle anything the mountain throws their way. Scarpa added a removable EVA insulated liner, which keeps your toes toasty in harsh cold and can be dried in your sleeping bag at night. It goes without saying that these double boots feature full step-in crampon compatibility.
