BESTSELLERS
Every model is tested at the CTCP to ensure durability, flexibility, and long-lasting quality. Each pair is then assembled by hand for 5 to 6 hours and passes through the hands of around twenty artisans, with quality checks at every step.
Because a sustainable shoe is, above all, a well-designed, masterfully crafted shoe meant to be worn time and time again!
Before you wear them, we test them on our own feet. Every new model is worn and tested for several months, then evaluated by the CTCP, the Portuguese technological centre specialised in footwear. If it isn't perfect yet, we refine and try again.
And clearly, it works: 90% of our customers confirm their comfort!
At Zèta, we love looking where no one else does. Grape pomace, olive skin, coffee, or corn—we turn upcycled by-products into desirable shoes! We test, refine, and start again… until we find the perfect material, the right feel, and the ideal finish. Because true innovation isn't about being different just to be different, it's about doing better with less.

FAQ
Why choose Zèta?
At Zèta, we firmly believe that a sustainable shoe must first and foremost be a shoe you truly want to wear. That is why we design timeless styles, handcrafted in Portugal from innovative materials such as corn, coffee, olive, grape, and even recycled tennis balls. Comfortable shoes, designed to last and accompany you every single day.
Where are Zèta shoes made?
All our shoes are handcrafted in our family partner workshops in Portugal. Each pair requires nearly 6 hours of craftsmanship—the time needed to bring a high-quality, durable shoe to life.
Are Zèta shoes comfortable?
Yes, and it is truly one of our greatest strengths. Before reaching your feet, every pair is tested at the CTCP, the Portuguese Technological Footwear Centre, and worn for several months by our teams.
And it shows: over 90% of our customers tell us that their Zèta shoes are exceptionally comfortable.
How do I care for my shoes?
To keep your Zèta shoes looking their best for as long as possible, we recommend waterproofing them before the very first wear and caring for them with products tailored to their material. For suede-effect styles, opt for a special brush or cleaning eraser, without using water. Find all our advice in our care guide.
How do I choose my size?
Choosing your size online isn't always easy. That's why we created a comprehensive size guide, featuring specific recommendations for every style.
And if you are still unsure, our team is here to help: hello@zeta-shoes.com. We will be delighted to advise you!
Are Zèta shoes truly vegan?
Yes! All our shoes are 100% vegan and contain no animal-derived materials. Instead, we develop plant-based and recycled alternatives, selected for their premium quality, comfort, and durability.
