At Zèta, by partnering with Labfresh, we were not simply looking to create a beautiful trainer. We wanted a plant-based material capable of withstanding the reality of your daily life, while keeping your feet cool.

A plant-based material, but robust

The maize used for the upper of this trainer comes from crops guaranteed 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 genuine scratch-resistant shield against everyday friction, while maintaining a neat, 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, the entire architecture of the shoe is designed to last. Hand-assembled in Portugal using a Strobel construction renowned for its robustness, it sits on a sole made from 50% recycled rubber. Inside, the 100% recycled memory foam insole guarantees absolute comfort.

A trainer that does exactly what is asked of it: accompanying you for a long time, comfortably, without ever wearing out.
