Committed to make timeless sneakers and use them as a vehicle for change.


We use leather that’s certified by the Leather Working Group (LWG) for the upper part of our sneakers. We buy the leather from our Portuguese supplier, who gets it mainly from European cows.

When we started SAYE one year ago, we realized that until the meat industry stops, leather would be a sub-product that if not used, will end up in landfills. We would never kill for the leather but the truth is that there are very little “non-fuel-based” available materials on the market that simulate leather that can be used for the upper part of the shoe.

These now called “vegan” materials are mainly synthetics and microfibers, generally made of virgin plastic and are far from being biodegradable, so definitely that is not a solution for the environment either. Nevertheless, leather is a readily available waste product with great design possibilities that performs exceptionally well in terms of breathability, durability and comfort.

However, we are already testing new recycled materials and hope to introduce them in the near future.  


We use organic cotton that’s certified by the Global Organic Textile Standard (GOTS) for the linings and laces. GOTS is the worldwide leading textile processing standard for organic fibers, including ecological and social criteria, backed up by independent certification of the entire textile supply chain. A product with this label ensures a minimum of 95% of organic fibers.

Becoming GOTS certified is by no means easy, but to us there is no other way. GOTS helps ensure that our organic cotton is sourced in the most ethical and sustainable ways from seed, to stitch, and finally, to sleep.

Organic cotton is beneficial for our environment and our health because it is grown in fertile landfields that are free of pesticides, herbicides and synthetic chemical fertilizers, and in addition it is spun and produced without toxic chemicals. Additionally, organic agriculture respects the cycles of Earth, trying to maintain a balance preserving the land for future uses.

Every time we use a certified organic product on our sneakers, we are getting both socially and environmentally committed, we are betting on a slightly cleaner and safer world, and we are helping the Planet and our future generations.


Our outsole is made in Portugal and composed of 30% natural rubber and 70% synthetic rubber as this mix allows maximum performance and comfort.

Using only natural rubber would mean production problems as it is a material too flexible to work with. Apart from that, 100% natural rubber outsoles are more slippery and they get worn out more easily too.

We will be introducing recycled rubber very soon since our aim is to reduce waste drastically.


We recover Polyurethane (PU) leftovers from European automotive factories that otherwise would become waste, and we transform it into brand new insoles made out of 60% recycled PU + 40% virgin PU.

Our insole is especially designed and developed in perfect harmony with the environment, with excellent physical and mechanical properties. Its key component, Carbon, is a plant-based substance that has absorbing properties and has also breathability and desorption properties, which eliminates moisture, thermal sensation and unwanted odors.


The counter and the puff of the sneakers are invisible stiff piece reinforcements positioned between the lining and the upper, that help maintain the shape of the shoe. The counter helps strengthen the rear of the shoe and the puff helps the toe cap.

We recover thermoplastic leftover plates and we transform them into new puffs and counters, adding also up to 35% of wood chips recovered from the carpentry industry.


We use 100% recycled boxes and paper manufactured in Portugal with the Forest Stewardship Council (FSC) and Programme for the Endorsement of Forest Certification (PEFC) certifications.

When timber leaves an FSC or PEFC certified forest we ensure companies along the supply chain meet our best practice standards, so when a product bears the FSC / PEFC logo, you can be sure it’s been made from responsible sources. In this way, both certifications help forests remain thriving environments for generations to come, by helping you make ethical and responsible choices.
