Precision and comfortable fit are the main qualities of VIAZ GTX. A shoe designed for intense hiking activities up to medium altitudes, but especially for vie ferrate and alpine-style normal routes. The protection on the areas of greatest friction and the adoption of IMS1 grant accuracy and safety even on the roughest trails without sacrificing the immediate comfort of fit.

AIR 8000® is a unique technological solution utilised by AKU for engineering a breathable upper with the correct thermal balance. Laboratory tests confirm that AIR 8000® offers up to 11 times greater breathability than a traditional fabric over a period of 24 hours.
IMS The Internal Midsole System is an exclusive technology used in the construction of the AKU insole. It couples the traditional support structure in nylon to a layer of microporous material at the interior of the upper. This system, which allows for the sole to perfectly capture the anatomy of the foot, ensures a uniform distribution of pressure, prevents from lateral and frontal slipping under heavy use, and provides shop absorption for an excellent wearing comfort.
The version ISM1 combines the System with an external midsole in a thin microporous EVA. In this way, thanks to the low profile of the midsole, it provides maximum sensitivity, precision and reliability to ensure a correct and instant reaction to uneven terrains.
