Olea Burgundy

Olive — What olive groves leave behind

The olive oil is extracted. What remains is usually forgotten. At Zèta, that is where everything begins. Skins, stones, olive fragments: all of these by-products, known as pomace, are crushed and transformed into material for shoes.

A by-product turned resource

After crushing, the olive pomace is blended with a water-based PU. The resulting paste is then dyed with natural pigments, spread onto a thick canvas, and heated to set its structure.

It is then cut in Istanbul and assembled in our workshops. This process minimises waste, upcycles olive by-products, and offers a viable alternative to less sustainable 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 for plant-based alternatives sourced from olive groves.

Why use it?

Because it provides genuine durability, excellent resistance to daily wear, and a clean, understated finish.

And because repurposing agricultural co-products is a tangible way to produce differently.

Your feet carry you, take good care of them.

At Zèta, comfort is not an afterthought, it is our starting point. Where many brands focus solely on style, we choose to combine aesthetics, ethics and well-being at every stage of development of our trainers.

Our models are designed to adapt naturally to your foot: supple, lightweight, and breathable, they make you feel like you are walking in slippers – and that is exactly what over 90% of our customers tell us in their reviews. So it is not just us saying it, it is you.

The secret? We use the Strobel construction, a premium manufacturing technique that gives the shoe exceptional flexibility. The result: natural cushioning, no feeling of stiffness, and incomparable freedom of movement, even after hours of walking.

No more blisters and heavy legs: our trainers go with you everywhere, in the city as in the woods, from the first to the last step of the day.

Trainers made to last, without compromising on comfort.

Our materials are carefully selected to ensure they are pleasant to wear and durable over time. Before being launched, all our prototypes are inspected by the CTCP (Footwear Technological Centre of Portugal) for flexibility and abrasion testing. Then, they are tested in real-world conditions by our team and Zèta club members.

Each pair is assembled by hand by our Portuguese artisans, then subjected to rigorous quality control to ensure that your comfort meets our high standards – and yours.

Manufacturing workshop - Vizela, Portugal

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

At the age of 20, Albano assembled his very first pair of shoes in the back of a garage. 

His first pairs of shoes were then sold in a few local shops and after Sunday mass. The shoes proved popular thanks to their quality and were quickly sold all across northern Portugal.

For over thirty years, nearly 150 artisans have been keeping Portuguese craftsmanship alive with meticulous attention to detail and finishes. They joined our journey in 2022, and over the months we have forged very strong relationships.
