ISPO Award Winner 2024: Mammut Aenergy Ultra Mid/Low GTX hiking shoe

With the Aenergy Ultra Mid or Low GTX, Mammut merges trail running technology with hiking needs, catering to outdoor enthusiasts who seek both lightness and protection, along with stability on challenging mountain terrain. "With the Aenergy series, we have realized our vision of delivering a new echelon of hiking footwear, unparalleled in efficiency. This fusion of protection, stability, and lightness is distinctive, encapsulating the essence of our brand while providing enhanced cushioning and the ability to hike faster on mountainous trails“, explains Oliver Korden, Teamlead Footwear at Mammut.

The Aenergy Ultra is available in both low and mid-rise versions and is a top-tier shoe for contemporary hikers who desire a more efficient stride without compromising on stability. An Ortholite insole ensures high comfort, while a cushy midsole provides up to 15 percent more shock absorption. Additionally, an integrated stiff plate enhances stability and control.

“In the Aenergy Ultra, we've pushed the boundaries, achieving peak cushioning and protection. Hikers will revel in the augmented cushioning and fluidity of motion afforded by our sophisticated midsole design“, Oliver Korden proclaims enthusiastically.

The midsole packs considerable performance; thanks to the Vibram SLE EVA midsole, the shoe is lightweight and offers maximal cushioning. The Flextron shank delivers dynamic control, torsional stability, and stiffness, which boosts toe-off efficiency—in other words, it reduces energy expenditure, enabling hikers to move faster and further. The result is maximum responsiveness from these combined features.

The Vibram Megagrip Litebase outsole with Traction Lug offers superior grip in both wet and steep conditions, and the Gore-Tex technology keeps feet dry.

While rockered shapes have been common in running gear but less so in hiking recently, this modern design ensures a smooth landing and effortless toe-off in the Aenergy Ultra. The progressive design aims to highlight its suitability for tough mountain terrain. The Lenzi fabric upper, made from a single piece, underscores this advanced application, being a highly abrasion-resistant and seamless mesh material. 

Overall, the Mammut Aenergy Ultra delivers maximum cushioning, responsiveness, and stiffness, ensuring dependable performance during fast hikes in challenging mountain environments.

„Wearers will enjoy a day on the trails, ensconced in the assurance of robust yet breathable and lightweight upper materials. The contemporary aesthetic belies the footwear’s capabilities, skillfully concealing the ruggedness typical of heavier, more traditional hiking boots”, Oliver Korden, Team Lead Footwear at Mammut sums up. And the ISPO Award jury also agreed: This shoe is a performant hiker packed with progressive technology and a contemporary look and feel.
