These storming new boots are a must-have for alpinism, where their light weight, high warmth and sheer dexterity prove ideal for steep ice, hard mixed and classic long alpine routes. The snug inner boot features superstrong Dyneema laces and a Fast Lock tightener to make adjustments easier for gloved hands. The multi-layer outer boot features a tough S-Tech outer, waterproof membrane, EVA/Aluminium, felt reinforcement and Primaloft lining. A waterproof TIZIP with oversized pull tab and a high waterproof mini gaiter complete the weatherproofing while the sole unit combines a TPU midsole, PU inserts for top shock absorption and an awesome Vibram Total Traction outsole. Developed with input from Eiger North Face speed solo record holder, Ueli Steck. Available in selected stores only.
