AKU Viaz DFS GTX
The VIAZ DFS GTX from AKU is the ideal companion for demanding mountaineering activities. Whether hiking, on via ferrata routes, or on high-altitude tours—this versatile mountaineering boot impresses with its semi-crampon-compatible construction, which was specifically developed for fast mountaineering. Thanks to the waterproof Gore-Tex® membrane, your feet stay dry even in adverse weather conditions, while the high shaft provides additional support and protection.
Particularly noteworthy is the innovative VIBRAM LITE BASE technology, which enables a lightweight design without compromising stability and precision. This makes the VIAZ DFS GTX a reliable companion on the most challenging trails. The 130 cm-long laces ensure an optimal fit and a secure hold, which is particularly advantageous on rough terrain.
These boots are not only popular among mountaineers, but are also highly valued by rescue teams on alpine missions. Their ability to provide extreme flexibility makes them an indispensable piece of equipment when it comes to responding quickly and efficiently to changing conditions.
