FAQ
FAQ
Before launch, each of our prototypes is tested by the CTCP (Footwear Technology Center of Portugal) to perform flexibility and abrasion tests. In addition, our prototypes are tested in real-life conditions within our team and by select 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 the end of each production.
At Zèta, we place aesthetics, ethics and comfort at the heart of each of our product developments.
Thanks to their thick soles and 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 the city or in the forest!
We adapt each model so that they can adapt to the morphology of the foot (width, instep, heel) and the insoles are removable to slip in your specific insoles if necessary.
- If you live in and around Bordeaux, or are passing through the region, you can come and see, try on and potentially buy a pair of Zèta directly at our store at 41 rue Saint-François.
- If you're not from here and don't plan on dropping by, you can find most of our models in our points of sale spread across France and Europe, right here . To become a reseller and distribute Zèta, it's here that it happens .

The price of your Zèta,
it's clear.

Analyze to reduce.

Each component is carefully selected according to its durability and place of production.
- Exterior: 100% recycled PET canvas
- Inner lining 60% bamboo and 40% recycled PET
- Laces : recycled cotton (100%)
- Removable insole made from recycled foam (100%)
- Recycled synthetic rubber outsole (40%)
- Vegan glue made from resin
- Recycled polyester label
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 - Vizela, 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 at the age of 20 that Albano assembled his first pair of shoes, in the back of a garage.
His first pairs of shoes will then be sold in a few shops in the city and at the end of mass on Sundays. The shoes pleased with their quality and were quickly sold throughout the North of Portugal.
For more than thirty years, nearly 150 artisans have now perpetuated Portuguese craftsmanship by paying particular attention to details and finishes. They joined the adventure alongside us in 2022 and we have built very strong relationships over the months.
