The story of grapes,
transformed into a shoe.
The price of your Zèta,
it's clear.
Analyze to reduce.
Each component is carefully selected according to its durability and location of production.
- Exterior : Grape plant material made from wine production waste (25% wine waste 54% recycled polyester 21% water-based PU)
- Interior lining : mesh made from plastic bottles recovered from the Mediterranean (100%)
- Laces : recycled plastic (100%)
- Removable insole : recycled cork (100%)
- Outsole : recycled synthetic rubber (70%)
- Glue : recycled latex
The price of our sneakers is set precisely all year round according to the cost of raw materials and the remuneration of our artisans.
We achieve a margin of coefficient 3 which allows us to remain financially independent, while ensuring our growth: development of new innovative materials, recruitment and events.
For comparison, the majority of sneaker brands achieve a margin of coefficient 10.
Each pair emits 6kg of CO2 , compared to 15kg for a classic pair of sneakers.
We have carried out a life cycle analysis of our shoes, in particular using the ADEME tool, to understand their impact and be able to reduce it as much as possible.
This analysis takes into consideration the manufacturing and processing of raw materials, the manufacturing of shoes, their transport from Portugal to France, their use based on a period of 3 years, and recycling at the end of their life.
Your feet carry you, take care of them!
Comfort is often a feature overlooked by brands in shoe design.
At Zèta, we place aesthetics, ethics and comfort at the heart of each development of our products.
Thanks to their thick soles and their very soft lining, our shoes are real slippers (approved and recommended by osteopaths)!
No more blisters and leg pain: they will be your best ally for long walks in town or in the forest.
Accompany each of your steps, for as long as possible
Our materials are carefully selected so that you keep your sneakers as long as possible.
Before launch, each of our prototypes is tested by the CTCP (Footwear Technology Center in Portugal) in order to carry out flexibility and abrasion tests. In addition, our prototypes are tested in real conditions within our team and by certain members of the Zèta club.
The assembly of each pair is carried out by hand by our Portuguese artisans, and rigorous quality control is carried out at each end of production.
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.
