ISPO Award Winner 2024: Mammut Eiger Nordwand Advanced High GTX

Ideal for year-round, high-altitude tours, these boots excel in alpine challenges demanding low weight and high performance. »For this boot, we were working very closely with our athletes to enable their best performance in very challenging terrain«, says Lorenza Kessler, Product Manager Footwear at Mammut, explaining a little of the R&D backstory of this all year round, semi-crampon mountaineering boot.

The Vibram Litebase outsole delivers on both fronts, as it is lightweight and offers premium performance, which is why it was also requested by Mammut’s athletes. Meanwhile, GORE-TEX and Schoeller's Soft Gel insulation keep the feet warm and dry. The Ortholite O-Therm Insole adds additional support in keeping the feet warm, even in cold conditions, where an aerogel-infused foam provides an ultimate thermal barrier. Further, this boot includes Mammut’s patented contract control technology: A carbon plate in the PU midsole, that ensures lightweight rigidity. It minimizes weight but enhances stiffness by 20%.

The improved opening enables easy entry, and the BOA® Fit System offers a precise adjustable fit in the Mammut Eiger Nordwand Advanced High GTX. The dial is placed to the side. A zipper also enables a quick replacement of the BOA® Fit System if needed.

The overarching concept of this boot is minimal design for maximal performance. It has - same as the whole Eiger 6 collection - a focus on very durable design with a 100% PFC-free base that is repairable and while materials are used resourcefully in general.

The polyurethane-coated upper over a high-tenacity polyester core makes the shoe highly resistant to traction and abrasion. Woven directly into the fabric, these materials offer exceptional durability. The fact that it is resolable and the zipper can be replaced, enhances its repairability. Also, recycled polyester is used in the upper. The Mammut Eiger Nordwand Advanced High GTX helps to allow high-performing athletes to excel without compromising on lightweight, stiffness, warmth, durability, and repairability, which is also an impressive achievement in the eyes of the ISPO Award jury. The boot is unisex and a trustworthy option to support mountaineers on their mission in cold and challenging environments.
