The AKU shoe for all hikers seeking maximum protection and comfort. The new IMS3-Exoskeleton sole made of dual-density PU is lightweight and ranks among the top in the backpacking category. The AKU Superalp GTX is therefore the ideal shoe for hikes, such as the High Peaks of the Dolomites, as well as multi-day excursions in complete autonomy while carrying heavy loads on your back. In combination with the Internal Midsole System, the medium-density PU exoskeleton framework provides stability and protection. At the same time, the ultra-light polyurethane inner part offers shock absorption and pressure resistance. The exoskeleton technology of the sole is particularly well-suited for the Superalp GTX model. The midsole consists of an outer polyurethane skeleton that rises at the back to surround and protect the heel.
