This longstanding bestseller has been completely revised and now features an elastic fabric around the tongue, flex zone and on the heel collar. This has resulted in a huge increase in comfort and support in the boot. This effect is further enhanced by 3D-shaped heel cushioning, 3-zone lacing with efficient D-ring locking and the patented Base Fit 2.1. This is free sliding on the shoe outer above and below the heel bone using a Mammut Hammer cord, which significantly improves heel support and reduces blistering. Memo foam, an elastic GORE-TEX tongue construction and the GORE-TEX Performance Comfort Footwear membrane ensure the inside is dry and comfortable. The precise connection to the shaft is due to a light wedge made from poro, PU and TPU, which offers lasting cushioning. The proven Vibram Maton sole completes this updated crampon-compatible model, which is also suitable for demanding mountain hikes.

• The improved version of this patented technology with doubled, sliding heel strap elements made from original Mammut® cord. This significantly improves heel support, as the lines of force are distributed above and below the heel bone. The result is greater safety, increased precision and reduced blistering.
• Constructed from a blend of supple inner and tough outer materials, which means the boot is hard only where necessary and can be designed to fit the foot for enhanced comfort.
• The high-quality three-dimensional and infinitely variable memo foam cushioning provides an individual fit around the heel. This ensures high comfort together with maximum heel support and freedom from blisters.
• This roughly woven Italian textile of 73% polyamide and 27% polyester is very light, extremely resistant to abrasion and rip-proof. Permanent waterproofing prevents excessive water absorption.
• Premium quality foam cushioning which is worked into the instep, shin, and ankles of many Mammut models. The foam has excellent elasticity and returns to its original shape after being subject to intensive loads.
• The instep, heel pull and cuff are independently laced and secured, providing a first-rate fit for every shape of foot and activity.
• Asymmetric lacing adapts to the foot’s anatomy and enhances precise footwork as more pressure can be applied to the big toe.
• Three level wedge made from Poro, PU and TPU.
• The shape and arrangement of the studs gives this mountaineering and backpacking sole a secure grip on all kinds of terrain. The structured Climbing Zone provides stability on slippery surfaces. Soles can be replaced.
