La Sportiva N.A. Men's Nuptse Mountaineering Boot

La Sportiva N.A. Men's Nuptse Mountaineering Boot:
If you go where the air is thin and your only heat source burns from within, few mountaineering boots fit or serve you better than the double boot La Sportiva Nuptse. Beneath the insulated shell is a warm inner boot made with close cell polyurethane foam and sealed with an internal lace closure system. The inner bootie has tread on the bottom so you can wear it in base camp and never remove it while at altitude. The Nuptse is step-in crampon compatible and sized in half-size increments for optimal comfort.

• Insulated five-ply synthetic upper with a PU coating and a thermo-reflective aluminum coating
• Thermo-reflective aluminum coated lining treated with an anti-abrasion flocking
• Inner bootie comprised of high-density closed cell PE foam that's micro perforated for moisture transfer
• Lacing system on inner bootie for improved fit
• Tread on bottom of inner bootie (great for when nature calls at base camp)
• Board last construction (Nuptse last)
• 8 mm. reinforced Hytrel insole with a full-length, 2-mm. Dacromet coated steel shank with thermo-reflective aluminum facing
• S8R Aircushion midsole
• La Sportiva MPE sole with rubber rand
• Crampon compatible
• Weight: 6 lbs. per pair in size 41
