Moka Ristretto

Coffee — A material that brings your capsules back to life

Before being a shoe, the Moka is a residue. More precisely, coffee grounds. A by-product that is massively found in our consumption patterns—particularly via single-use capsules.

At Zèta, we don't see it as a leftover, but as a resource.

From coffee to shoes

The grounds are collected from a Nespresso sorting center in Portugal. They are first dehydrated in ovens, then mixed with a water-based PU. This dark paste is then spread on a cotton canvas before being cut and assembled by hand.

The resulting texture is soft, resilient, and slightly grainy. It is this deep brown material that gives Moka its name.

Locally rooted, designed to last

Made in Portugal, this material contains:

15% coffee , 50% cotton , 35% water-based PU .

It is mounted on our sneakers by our local artisans, with the same level of requirement as for our other models.

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 - Ovar, 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 in 1993 that Manuel Oliveira founded his own workshop, after spending his adolescence making shoes. A few years ago, his son Tierri joined the family business and its 25 artisans.

This team of true enthusiasts perpetuates artisanal assembly and pays particular attention to details and finishes. They were the first to believe in the beginnings of the project in 2019, and today they are at the heart of the brand.
