The Alterra II GTX from AKU is the ideal companion for demanding hiking and trekking trips. This high-quality men’s shoe is specially designed for long hikes and offers optimal protection against moisture thanks to its waterproof Gore-Tex® material. Whether you’re hiking in the rain or on wet trails, your feet will stay dry and comfortable. The high-cut design provides additional support and stability, while the 150 cm-long laces allow for a custom fit.
The upper of the Alterra II GTX is made of durable liba® smart PU, which is not only long-lasting but also easy to care for. The insole, made from a combination of 6–4 mm nylon and molded EVA, offers medium stiffness that ensures both flexibility and support. This design ensures that your feet remain well-supported and don’t get tired, even on longer hikes.
A special highlight is the free protective spray included with your purchase, which extends the life of your shoes and protects them from the elements. In addition, AKU offers a 2-year warranty on all products, so you can rely on the quality and durability of your choice. The Alterra II GTX is therefore not only functional but also an investment in comfort and safety on all your adventures.
