Corn — A plant-based material designed to last

At Zèta, we do not choose a material for how it looks, but for what it delivers. The corn we use is a solid, plant-based alternative suited for your everyday footwear.

A plant-based yet technical material

The corn used in our models does not come from the agri-food industry. It comes from non-food crops, avoiding competition with crops grown for human or animal consumption.

Once harvested, it is processed using a clean method: the dextrose extracted from the corn is fermented without petrochemicals, then transformed into a polymer. This polymer is then blended with a small amount of PU to create a durable material with a clean, smooth finish. Result: a reliable, vegan and breathable upper.

Designed for regular wear

The corn-based material contains 73% Bio-based PU and 27% recycled polyester. Its plant-based content reaches 50%, a threshold rarely crossed in the sneaker world.

Developed in Milan, the material is certified by several independent organisations:

PETA, Animal Free, USDA (organic certification), FSC®, ISO 14001, ISO 9001, ISO 45001.

A solid foundation for everyday trainers

Our Bêta, Alta, Velcro and Kids models are built around this material. It offers good support, withstands repeated friction, and keeps its shape over time.

It is also breathable and comfortable to wear. A material that does exactly what is asked of it, without overdoing it. It is often all you need.

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.
