Zèta x Labfresh Grey

At Zèta, by partnering with Labfresh, we weren't simply looking to create a beautiful trainer. We wanted a plant-based material capable of standing up to the reality of your days, while keeping your feet cool.

A plant-based material, yet robust

The maize used for the upper of this trainer comes from crops guaranteed to be pesticide-free. Processed using a clean method, this innovative plant-based alternative is composed of 73% Bio PU and 27% recycled polyester. The result? An extremely durable material that acts as a true scratch shield against everyday friction, while maintaining a clean, consistent appearance.

Technical excellence on the inside

This is where technical expertise truly comes into its own. The inner lining is also derived from cereals (28% cereal polymers, 62% recycled polyester and 10% PU). In practical terms, this composition makes it ultra-breathable and antibacterial. It retains eight times less moisture than a classic trainer. No more overheating: the material works for you, naturally regulating temperature to keep your feet cool, even after 12 hours of walking in the city at 32 degrees.

Designed for intensive use

Beyond the upper, it is the entire architecture of the shoe that is built to last. Assembled by hand in Portugal using the Strobel construction method, renowned for its robustness, it rests on a 50% recycled rubber outsole. Inside, the 100% recycled memory foam insole guarantees absolute comfort.

A trainer that does exactly what you ask of it: accompanying you for the long term, comfortably, without ever wearing out.

Your feet carry you — take care of them.

At Zèta, comfort is not a detail — it is a starting point. Where many brands focus solely on style, we take the challenge of combining aesthetics, ethics and well-being at every stage of our trainers' development.

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

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

No more blisters or heavy legs: our trainers go everywhere with you, in the city or in the forest, from the very first to the very last step of your day.

Trainers built to last, with no compromise on comfort.

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

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

Garment workshop – Vizela, Portugal

We are proud to work 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, at the back of a garage. 

His first pairs of shoes were then sold in a few shops in the city and after Sunday mass. The shoes were appreciated for their quality and were quickly sold throughout the north of Portugal.

For more than thirty years, nearly 150 artisans have been perpetuating Portuguese craftsmanship, bringing particular care to every detail and finish. They joined us on our journey in 2022 and we have built very strong bonds over the months.
