VIBRAM SOLES
Exclusive AKU Outsoles
Across most of its collection, AKU uses exclusive outsoles designed together with Vibram® — the specific design and shape of the outsole, and the composition of the rubber it is made with, engineered for each shoe's end use.
Why the Outsole Matters
The outsole is all-important for safety in technical footwear. AKU has always worked closely with Vibram® — the world's foremost manufacturer of soles for outdoor footwear — to meet every category of user's request for reliability and precision. Alongside the Vibram® products are specific solutions created exclusively by the AKU design department.
Three Segments
The Right Sole for the Way You Move
Every AKU outsole falls into one of three segments of the collection, each engineered for its terrain and use.
Mountain
- Particular resistance to abrasion
- Deep level of cleating
- Tread design with more space between cleats
- Greater weight and thickness
- Fewer component elements
- Crampon compatibility
Trekking
- Suitable resistance to abrasion
- Shock absorption, especially in the heel area
- Good cleating with correct cleat height
- Tread spacing that minimizes clogging
- Light weight
- Design allowing boot flex and protection
Active
- Particular resistance to abrasion
- Shock-absorbing capacity
- Extensive cleating with reduced cleat height
- Tread design that aids correct foot flex
- Remarkably light weight
- More component elements
The Partnership
Co-Designed in Italy
Both the tread geometry and the rubber compound of AKU's Vibram® outsoles are developed jointly for our footwear models — not pulled from a catalogue — so every sole matches the boot it's built for.
