AIR 8000
Laboratory tests confirm that the upper material made with the exclusive AKU system AIR 8000® offers up to 11.5 times higher breathability than normal standards with GORE-TEX®. Even after 20 years, the AKU system AIR 8000® remains one of the most modern technologies for excellent breathability of hiking shoes.

GORE TEX
The GORE-TEX® membrane offers an optimal combination of breathability and insulation, ensuring dry feet and optimal comfort for a wide range of outdoor activities - in all weather conditions.

INTERNAL MIDSOLE SYSTEM
The Internal Midsole System (IMS) is an exclusive technology applied in the construction of the AKU insole. The traditional support structure made of nylon is combined with a layer of microporous material, which is attached to the inside of the upper shoe. This system, in which the sole perfectly adapts to the anatomy of the foot, ensures even pressure distribution, prevents lateral and forward sliding under heavy stress, provides shock absorption, and maximum wearing comfort.

IMS 2
The version IMS2, combines the Internal Midsole System with a thicker midsole made of molded EVA or molded PU, for a correct interaction of sensitivity for the terrain and shock absorption. This combination ensures maximum fitting comfort and pleasant lightness when hiking.

WOMAN FIT
The lasts specially developed for the anatomical shape of the female foot are comfortable, enveloping and guarantee comfort and stability on uneven mountain paths.

ELICA
Elica is an integrated system that includes insole, midsole, and outsole, which replicates the shape of the foot sole, supports the normal inclination of the heel and forefoot, and thus reduces impact and stress.
