“Gravel YS” sole: Filtration & Stability
Yoann Stuck Edition - ULTRA
The first running insole to feature a carbon stability element!
The «Gravel YS» sole, developed in exclusive collaboration with champion Yoann Stuck, is designed for hybrid adventure. It meets the dual demands of both tarmac and off-road terrain. Our design team has therefore combined ultra-soft «Kinetic Absorb» cushioning to absorb shocks on tarmac, with a responsive structure capable of handling elevation changes and camber.
The addition of carbon optimises the response and handling of the crampons, delivering an extraordinary feel over short or ULTRA-long distances.
Care Instructions & Durability:
- Intended use: A versatile, high-performance design, ideal for mixed-terrain rides combining road and trails (Gravel, Road-to-Trail).
- Fitting: Easy to adapt and tailor to your trainers (see cutting instructions).
- To preserve the technical qualities of the materials, prefer natural drying away from sources of heat (direct sunlight, radiators).
Your ideal profile: A versatile runner (road and trail), a fan of ultra-distance running, looking for comfort and protection without compromising on performance.
