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 is not an afterthought — it is our starting point. Where many brands focus solely on style, we commit to combining aesthetics, ethics and well-being at every stage of our shoe development.

Our designs are crafted to adapt naturally to your foot: supple, lightweight and breathable, they give you the feeling of walking on air — and that is precisely what more than 90% of our customers tell us in their reviews. So it is not just us saying it, it is you.

Say goodbye to blisters and heavy legs: our shoes are with you every step of the way, from the first to the last stride of the day.

Shoes that last, with no compromise on comfort.

Our materials are carefully selected to be comfortable to wear and long-lasting. Before launch, all our prototypes pass through the hands of the CTCP (Centro Tecnológico do Calçado de Portugal) for flexibility and abrasion testing. They are then tested in real conditions by our team and members of the Zèta club.

Each pair is hand-assembled by our Portuguese artisans, then subjected to a rigorous quality control process to ensure your comfort meets our standards — and yours.
