Vibram is synonymous with the sole for mountain footwear, an essential component for the safety and technical performance of the product. Vibram’s experience is condensed in the research and development of specific compounds for use on different terrains and environmental conditions; AKU’s contribution is based on the design of the tread profile, conceived and designed according to the intended use of the product. From this synergy are born soles that AKU adopts on many of its models, generating its own exclusive standard of performance.

The sole design

The sole is one of the elements that make up the shoe and must be considered as part of a single project, consistent with the technical / functional needs of the type of shoe that is being designed and the last on which it will be built. In the case of AKU, the sole must copy the anatomical and helical shape of the bottom of our last, in order to support and enhance its anatomical and dynamic characteristics.
Another aspect to pay attention to is its reliability which must also be consistent with the use for which the shoe was designed, with a view to minimizing material waste to obtain the maximum required result.
A further element of attention is the search for the simplicity of interface / assembly between the sole and the other components of the shoe. In summary: maximum attention to the minimalism of the sole, both in weight and in the components and design choices.

The Megagrip compound

A special compound designed by Vibram ® to offer excellent grip on dry and wet surfaces. This compound today represents the highest standard in field performance for Vibram compounds dedicated to outdoor and sports footwear. Perfect mix of grip and durability, Megagrip expresses an excellent balance between stability and flexibility on all types of terrain. AKU adopts the Megagrip compound on some of its higher technical performance models.

Arctic Grip

Vibram Arctic Grip is the most advanced Vibram system to guarantee grip even during the winter season. Specifically designed for slippery and icy surfaces.

Vibram N-OIL

Vibram N-OIL compound is another innovative solution from Vibram®, designed to offer a green alternative in the footwear world.
Composed of more than 90% natural ingredients, while maintaining the performance and qualities of Vibram. This compound is also made without the use of solvents or chemicals.
This is a step forward made by AKU and Vibram® in their constant search for innovations and high-performance, responsible products. AKU uses the N-OIL compound on some of its environmentally responsible models.

Traction Lug

Vibram Traction Lug is a new design focused on the key element in traction. Vibram® has developed the tread with micro lug-shaped features, increasing the ground contact surface by 50%. Vibram® thus provides up to 25% better traction and improved stability during use.
AKU has decided to use this technology in footwear that needs high performance and better grip, especially when pushing.


Mountain soles are characterized by:

a particular resistance to abrasion an accentuated sculpting the background design with a number greater than blanks the particular heaviness and thickness fewer elements of which they are composed.


Trekking soles feature:

an appropriate resistance to abrasion shock absorption capacity, especially in the heel area an accentuated, characterized sculpting from a correct height of the caps bottom design which includes empty areas for cleaning the bottom attention to lightness a design that allows for flexion and boot protection.


Multiterrain soles have common characteristics:

a particular resistance to abrasion shock absorption capacity an accentuated, characterized sculpting by a reduced height of the caps the design of the bottom that supports the correct flexion of the foot remarkable lightness more elements from which they are composed.
