OKTARA™
Post-consumer rubber. Uncompromised performance.
A rubber compound engineered for footwear outsoles, made from end-of-life sport shoes and tennis balls. Ready to spec on your standard soling process. Already in production at Veja and Decathlon.

What OKTARA is
The outsole decides
Outsole rubber is never a raw material. It's always a blend, built to hit specified targets: grip, abrasion resistance, rebound, hardness, behaviour on release from the mould.
OKTARA™ starts from regenerated post-consumer elastomers and is formulated against your spec, batch after batch.
Performance comes from the formulation.

Rubber back into rubber
Recovered rubber usually finds a home somewhere less demanding. A softer application, a lower bar.
Ours goes back where it came from. Shoe rubber becomes shoe rubber. Same application, same requirements, same manufacturing process.
That's the difference between finding a use for a material and keeping it in its own loop.
Howthe performanceis made
Five steps, from an end-of-life shoe to a compound your factory can mould. Powered by THE 8 IMPACT patented industrial process.
Over 3,000 end-of-life products analysed and sorted into qualified categories. Every batch is registered from intake, and its composition established by statistical extrapolation. We know exactly what goes into the line, and so do you.

TRACE
Look closely at the compound and you'll see specks in the material.
They're the only things in that outsole that have already run.
We could smooth them out. We keep them, and that's a decision. Grain on film, figure in wood: proof that something real existed before.
Performance has memory.
Compliance
Cleared for your spec sheet
REACH-compliant. Every OKTARA™ compound carries its own life cycle assessment, alongside toxicology. Traceable from intake through delivery, batch by batch.
Engineered to match virgin rubber on spec, at competitive cost on the measured case.
Made in Bourg-en-Bresse, France. Designed, processed and looped in Europe.
Circularity
The loop is already running
30% regenerated content in the rubber fraction, as a standard. Today, on shoes people are wearing.
How it's measured
Each compound carries its own assessment. The figure moves with the material, so we give it per compound rather than as a headline.
Choose OKTARA™ because it holds your spec. The loop comes with it.
Here, circularity is a production standard rather than a promise.
