AKU Alterra Lite GTX Anthracite/Light Blue 38 Udendørssko til kvinder

Lightweight footwear, versatile and breathable, for dynamic use on terrain of medium difficulty. The shoe upper is made up of two structures: an external one in suede with independent features which wrap around the foot anatomically and support the anatomy of the foot.

AIR8000

AIR 8000 is the first technology for the construction of the upper developed and patented by AKU since 1991 to increase the breathability of a mountain shoe.

• Laboratory tests carried out by Gore Tex confirm that the upper made with the exclusive AKU AIR 8000® system offers a level of breathability up to 11.5 times higher than normal standards. Almost 20 years later, the AKU AIR 8000® system remains one of the most advanced technologies to ensure excellent breathability of the mountain shoe.

TENUTA GRIP

Tenuta Grip is the name that identifies a special compound developed by AKU for some models in the hiking and speed hiking category. A compound and tread designed for mixed and off-road use, for a special grip on smooth and wet surfaces.

ELICA AND THE AKU LAST

The creation of a last is a long and accurate process in which AKU’s long experience in the design and production of high quality footwear is condensed. The identification of the last in relation to the morphology of the foot represents one of the basic criteria in choosing the right shoe.

• The original AKU shape is the matrix, the result of constant research on plantar anatomy. From it, thanks to specific adaptations, the different types of shape and fit derive, which vary in relation to the different models and the specific function of use of the product.

Elica is an integrated system consisting of FORMA – ASSEMBLY INSOLE – MIDSOLE – TREAD that follows the anatomical shape of the sole of the foot and follows the normal inclination of the heel and forefoot. The functional value of the ELICA technology has been certified by specific tests performed at the CERISM Centro Studi Salute laboratories of the University of Verona. The tests show that a more homogeneous distribution of foot pressure during the support and push phases favors comfort by reducing impact and effort during the walk.

• The support phase: During the support phase, the assembly insole is inclined outwards to support the support of the heel. In the external area of the heel the shock-absorbing thickness is greater to absorb impact, while the internal front area of the wedge is made of shock-absorbing material to distribute the thrust force. The asymmetrical design of the tread aligned with the support axis and the protruding profile increase the contact surface.
• The propulsion phase: The assembly insole is inclined inwards to accommodate the support of the forefoot, which naturally rests inwards. The internal front area of the wedge is made of shock-absorbing material to distribute the thrust force and also the tread caps protrude outwards to increase the support surface.

GORE - TEX®

• The Gore-Tex® membrane is an exclusive heat-sealed technical fabric which contains about 1.4 billion microscopic pores per square centimeter. These pores are approximately 20,000 times smaller than a drop of water but 700 times bigger than a molecule of moisture vapor. So, whilst water droplets cannot penetrate the GORE -TEX membrane, moisture vapor, namely perspiration in gas form, can easily escape.
