Aku Men's Superalp Therm GTX

Engineered for serious winter adventures, the SuperAlp Therm GTX is built to handle the harshest conditions—whether you’re crossing frozen ground, pushing through deep snow, or carrying a heavy pack on long cold-weather expeditions. With high thermal insulation and a rugged build, this boot is equally reliable for winter hunts and demanding outdoor work.

Crafted in premium Italian full-grain leather with a protective rubber toe rand, the upper offers durability and long-lasting performance. Inside, a GORE-TEX® Insulated Comfort lining locks in warmth while keeping moisture out, ensuring dry feet no matter how wet or cold the environment. Underfoot, the Vibram® Fourà outsole delivers dependable traction on snow, ice, and mixed terrain, while the dual-density PU midsole provides cushioning and support mile after mile.

Every detail is designed for stability and comfort under load. The stiff lasting board adds structure for carrying weight, and the Custom Fit IMS footbed enhances fit and shock absorption. At just 760 grams per half pair, the SuperAlp Therm GTX balances strength with efficiency, further optimized with AKU’s exclusive ELICA Natural Stride System, which improves walking dynamics and reduces fatigue on long winter days.
