AKU has for most of its shoes the exclusive outsoles designed together with Vibram®, for both the specific design and shape of the outsole as well as for the composition of the rubber which it is made with, thought for the specific needs and the different use of the shoes.
GORE-TEX®
GORE-TEX® Footwear is a breathable, microporous yet completely waterproof membrane. This is achieved by virtue of the fact that each of its pores is 700 times bigger than a molecule of water vapour but 20.000 times smaller than the smallest possible drop of water. Its chemical and physical qualities remain unchanged through time and render GORE-TEX® Footwear bio-compatible and immune to chemical and acid attacks. The GORE-TEX® Footwear with XCR® fabric is W.L.Gore's newest technology. It is developed due to the high demand of an extremely breathable and durable garment GORE-TEX® Footwear with XCR® fabric is built into everyday shoes and outdoor activity boots, making them totally waterproof while keeping feet cool and dry.
AIR 8000
During any kind of sport activity, the body removes the excess heat through perspiration. This happens also to the foot, particularly among the toes and through the sole. It is therefore very important for the comfort of the foot to remove this perspiration from the foot itself and drain it in some way outside. AKU , to attain this goal, has created AKU AIR 8000®. This is a fabric used in the construction of the uppers. This material is protected by an international patent and it has been specifically designed to guarantee perfect breathability. A high, breathable performance level is very important for the health of the foot. If a foot is well aerated, it is not attacked by micosis, skin infiammation and painful blisters. It is demonstrated by accurate laboratory tests that, over a period of 2 hours, AKU AIR 8000® transpires 8021 grams of vapour, while in other traditional fabrics, the transpiration is of 700 grams only in the same time (2 hours). This means that AKU AIR 8000® transpires 11,5 times more than traditional fabrics. AKU is the only brand with this advantage. AKU has perfected the technique of allowing the upper of the boot to breathe while still supporting the foot.
Dynamic Energy Point
Dynamic Energy Point provides dynamic support. A piece of synthetic rubber inserted at the ankle facilitates ankle movement by assisting the foot's return to its starting position, thus saving energy when walking.
