Technology:



Elica:

- Elica is an integrated system consisting of LAST - INSOLE BOARD - MIDSOLE - OUTSOLE which faithfully follows the anatomical shape of the sole of the foot and adapts to normal heel and forefoot inclination to reduce impact and strain.

- Laboratory tests certify that footwear with Elica, compared to traditional footwear,

guarantees a more even distribution of foot pressure.



The tests highlight:

- a more even distribution of pressure during the entire stance phase

- a more central load at mid stance

- better arch support during midstance and lower pressure during the toe-off phase.



Heel strike:

- The insole board is inclined outwards to support heel strike, while in the external heel area the shock absorber is thicker in order to better absorb the impact. The asymmetric tread design aligned with the axis of stance and the elongated lugs increase the contact surface area.



Toe-off:

- The insole board is inclined to support the natural toe-off. The internal front part of the midsole consists of shock-absorbing material to distribute the push-off force. The lugs on the tread located on the inner part of the shoe are protruding outwards to increase the contact surface area.



Internal midsole system:

- IMS (Internal Midsole System) is an exclusive technology used in the construction of the AKU insole board. It couples the traditional support structure in nylon with a layer of microporous material.

- 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 shock absorption for an excellent wearing comfort.



Ims1 precise:

The version IMS1 combines the Internal Midsole 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.

Ims2 agile:

The version IMS2, couples the Internal Midsole System to a thicker midsole in molded EVA or molded PU, in order to create the right balance between ground control and shock absorption. Both, maximum comfort of fit and ease of walking are ensured.

Ims3 smooth mountaineering:

The Internal Midsole System is coupled with an Exoskeleton construction of medium density polyurethane for stability and protection, and a lightweight polyurethane inner part, which provides cushioning, shock absorption and high compressive strength. In addition, it features a lightweight and durable TPU heel cap and a rubber toe cap for a perfect fit of the crampon.

Ims3 smooth trekking:

- The Internal Midsole System is coupled with an Exoskeleton construction and a further internal component made of Molded EVA. The external structure of lightweight polyurethane, a resistant, solid and durable material, provides protection and support at the key points of the foot to ensure a safer step. The layer in Molded EVA is made of a softer material for an ideal cushioning and shock absorption and thus making the hike extremely comfortable.

- Exoskeleton in pu

- Vibram® sole



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. GORE-TEX®® has developed 3 specific types of membrane for the footwear sector, each with specific functional properties.

Goretex® surround™:

- Hiking shoes/boots engineered with GORE-TEX®® SURROUND™ product technology are designed for outdoor use in moderate to warmer conditions.

They offer enduring waterproof protection and optimum breathability all around the foot. Moisture and warmth also escape through the GORE-TEX®® membrane into the open structure of the “spacer” - and from there out of the shoe via side ventilation outlets. the result is faster sweat removal rate, keeping your feet dry and comfortable even at higher temperatures.
