The Hayatsuki GTX from AKU is the ideal companion for demanding hikes and high-altitude tours in alpine regions. This men’s boot was specifically designed for use in challenging and mixed terrain and offers outstanding performance up to an altitude of 4,000 meters. Thanks to its waterproof properties and high-quality leather, your feet will stay dry and protected even in adverse weather conditions.
With crampon-compatible construction and a high-cut design, the Hayatsuki GTX offers optimal support and stability, which are essential for mountaineering and high-altitude trekking. The lacing system, featuring 180 cm-long laces, ensures a customizable fit and a secure hold. The robust upper, made of RUBBER RAND and LIBA®SMART PU, protects the shoe from wear and tear and ensures its durability.
The stiff insole, made of 6-4 MM GLASS FIBER and DIE-CUT EVA, provides excellent support and cushioning to ensure comfort even after long distances. This boot combines thoughtful design with innovative materials to deliver both comfort and performance at the highest level.
