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.



PRECISE FIT:

- Precise, slightly curved lasts for footwear in the Backpacking and Multiterrain segment, designed for a dynamic use on medium difficulty terrain or more demanding on technical surfaces.



RELAXED FIT

- Soft and comfy lasts for footwear in the Mountain Inspired segment, designed for light outdoor activities, in undemanding conditions.



THE ULTRA-RELIABLE MULTITERRAIN SOLE:

- Developed exclusively for AKU, the new MICHELIN Pulsar Technical soles is the product of a close collaboration between a team of skilled footwear specialists.

- Drawing on MICHELIN’s own extensive ground contact expertise, the MICHELIN Technical Soles designers worked hand-in-glove with AKU management to create an all-round high performance product that adapts easily to all kinds of terrain and conditions, making it a real “must have” for outdoor enthusiasts.

- The combination of the MICHELIN Technical Sole and the AKU Elica-Natural Stride System, which accommodates the foot’s anatomy and biomechanics to support the natural inclination of the heel and forefoot, results in more even weight distribution on the sole of the foot both as it lands and pushes off again.

- The MICHELIN Pulsar sole was developed to accommodate the Aku Elica-Natural Stride System, with an asymmetric design for ground contact (1) in line with the natural stride axis. It takes its inspiration from the MICHELIN Wild Grip’R Descent mountain bike tyre which itself was developed for downhill cycling on mixed terrain, with progressive lateral grip and a motocross-derived tread pattern.

- All in all, it’s a good test bench for a sole made to tackle all kinds of ground surfaces, something it can accomplish effectively thanks to deep grooves that boost adaptability to very different kinds of terrain (2).

- In addition, the sculptures are positioned in irregular groups to focus on the areas of greatest stress. Smaller and more aggressive sculptures under the big toe deliver progressive traction (3), while aggressive shoulder sculptures improve lateral traction and stability (4).

- Bridge reinforcements also achieve the same for stability and wear resistance (5).

- Massive sculptures at the heel boost braking ability (7).

- A high distance ratio between the sculptures also facilitates selfcleaning (6), while two flexion channels make for greater flexibility when the foot is rolling.



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.



Extended comfort:

- Ideal for moderate or warmer weather conditions. Exceptional performance in high-output activities and everyday use.



Key advantages:

- Optimum heat conductivity and excellent moisture management ensure all-day climate comfort inside the shoe.

- Durable waterproof protection.



Performance comfort:

- Moderate insulation to keep feet dry and comfortable during outdoor activities in a variety of weather conditions.



Key advantages:

- Moderately insulated for changing conditions

- Optimal combination of breathability and insulation keep feet warm and dry, even in unexpected weather

- Durable waterproof protection



Insulated comfort:

- Offers a range of insulation options to keep feet dry and comfortable in cold to very cold temperatures. Designed for the winter, they keep feet warm and dry all day long, even in rain, snow and ice.



Key advantages:

- Various insulation options available, enabling selection of the right

shoe for a particular winter activity

- Optimal combination of breathability and insulation keeps feet

comfortable, never sweaty

- Durable waterproof protection keeps moisture out



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.



Injection lasting:

- AKU uses a special removable last for injected footwear during the complete production process, when lacing, across assembly right through to cooling and finishing.

- No other injected footwear manufacturer keeps the last inside the boot throughout this process, especially during the last two stages, the most critical ones. During the cooling stage, after injection, the polyurethane sole memorizes its shape. This is also the stage when the polyurethane naturally shrinks therefore if the last is removed the whole boot loses its shape.
