Olea Vert

Olive — What the olive groves leave us

Olive oil is extracted. What's left is usually forgotten. At Zèta, that's where it all begins. Skins, pits, olive fragments: all these residues, called pomace, are ground and then transformed into shoe material.

A by-product turned resource

After grinding, the pomace is mixed with a water-based PU. The resulting paste is then tinted with natural pigments, spread on a thick canvas, and then baked to stabilize its shape.

It is then cut in Istanbul and assembled in our workshops. This process helps limit losses, optimize olive oil waste, and offer a viable alternative to other, less responsible materials.

A commitment to materials and products

The material is made of 87% olive , and 13% water-based PU .

It is developed under the Oleatex® certification, a benchmark in terms of plant-based alternatives from olive groves.

Why use it?

Because it offers real hold, good resistance to use, and a visual rendering that remains sober.

And because using agricultural residues is a concrete way of producing differently.

Your feet carry you, take care of them.

At Zèta, comfort isn't a detail; it's a starting point. Where many brands focus solely on style, we strive to combine aesthetics, ethics , and well-being at every stage of our sneakers' development.

Our styles are designed to fit naturally around your feet: flexible, lightweight, and breathable, they feel like slippers—and that's what over 90% of our customers say in their reviews. So it's not just us saying it, it's you.

The secret? We use Strobel construction, a high-end manufacturing technique that provides exceptional flexibility to the shoe. The result: natural cushioning, no feeling of stiffness, and unparalleled freedom of movement, even after hours of walking.

No more blisters and heavy legs: our sneakers accompany you everywhere, in the city as well as in the forest, from the first to the last step of the day.

Sneakers that last, without compromising on comfort.

Our materials are carefully selected to ensure they are comfortable to wear and durable. Before being launched, all our prototypes are tested at the CTCP (Footwear Technology Center in Portugal) for flexibility and abrasion tests. They are then tested in real-life conditions by our team and members of the Zèta club.

Each pair is hand-assembled by our Portuguese artisans and then undergoes rigorous quality control to ensure your comfort meets our standards – and yours.

Clothing workshop - Vizela, Portugal

We are proud to collaborate with partners who share our values ​​and are as committed as we are, both environmentally and socially.

It was at the age of 20 that Albano assembled his first pair of shoes, in the back of a garage.

His first pairs of shoes will then be sold in a few shops in the city and at the end of mass on Sundays. The shoes pleased with their quality and were quickly sold throughout the North of Portugal.

For more than thirty years, nearly 150 artisans have now perpetuated Portuguese craftsmanship by paying particular attention to details and finishes. They joined the adventure alongside us in 2022 and we have built very strong relationships over the months.
