FAQ
A barefoot shoe is designed to respect the foot’s natural movement.
Closer to the ground, it leaves more room for the toes and supports your movements for a freer, more natural walking sensation.Classic trainers are often designed with more cushioning, support and thickness.
Barefoot trainers follow a different approach: they bring the foot closer to the ground, offer more room for the toes and allow the foot to move more freely.Barefoot shoes are inspired by the way our feet have naturally evolved to walk: freely, with room to move and feel the ground.
At Zèta, we believe the foot does not need correcting; it needs its space back!A barefoot design that gives the foot more freedom, paired with a sleek silhouette inspired by our trainers.
Like all our pairs, they are handmade in Portugal from vegan and recycled materials, selected for their quality and durability.Delivery and returns

Vegan suede — An animal-free material
At Zèta, we do not choose a material for what it appears to be, but for what it can achieve.
Our vegan suede is a great alternative. It retains its soft, textured finish without any animal origin, and stays durable over time.
Animal-free yet technical suede
Our vegan suede delivers everything you expect: a velvety finish, a matte texture, and a pleasant feel. It contains no animal fibres, yet remains supple, durable, and comfortable to wear.
Designed for everyday wear, it maintains its shape even after being worn many times. It withstands friction, cleans easily, and keeps its natural look without stretching out.
A reliable material for everyday wear
Our vegan suede is used on several Zèta models. It structures the silhouette, adds depth to colours, and stands the test of time.
Comfort begins by letting the foot move.
At Zèta, comfort is not a detail; it is our starting point. With our barefoot collection, we wanted to go further: give the foot more room and support its natural movements, without compromising on aesthetics, ethics or comfort.
A wider toe box, a thin, flexible sole and zero drop: every detail has been designed to recreate the feeling of walking barefoot. The foot can move more freely, the toes have more room and contact with the ground feels more natural.
The secret? We use Strobel construction, a manufacturing technique that gives the shoe exceptional flexibility. Combined with a thin, flexible sole, it allows the shoe to follow the foot’s movements rather than restrict them.
Durable craftsmanship, with no compromise on comfort.
The barefoot collection is lightweight, flexible and breathable, designed to support you every day. A different approach to footwear, created for those who want to rediscover more sensation with every step.
Our materials are carefully selected for their comfort and long-lasting durability. Before launch, our prototypes are tested at the CTCP (Footwear Technology Centre in Portugal), particularly for flexibility and abrasion resistance. They are then tested in real-life conditions by our team and members of the Zèta Club!
Finally, each pair is assembled by hand in Portugal in our partner workshops, then subjected to rigorous quality control.
A different way of thinking about footwear. More room for the foot, more freedom with every step.
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.
