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 prioritize style alone, we make it our mission to combine aesthetics, ethics , and well-being at every stage of our shoe development.

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

No more blisters and heavy legs: our shoes accompany you everywhere, from the first to the last step of the day.

Shoes that last, without compromising on comfort.

Our materials are carefully selected for their comfort and durability. Before being launched, all our prototypes undergo flexibility and abrasion testing at the CTCP (Technological Center for Footwear in Portugal). They are then tested in real-world conditions by our team and members of the Zèta club.

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