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


We use leather from our Portuguese supplier, who gets it mainly from European cows. Our leather is environmentally certified, assuring that environmental stewardship procedures have beengranted during all the leather working process, from manufacturer to final product.

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 certified organic cotton for the linings and laces. The cotton used fulfill the requirementson best organic fibers, including certificates on respectful ecological and social standards.

Organic cotton is beneficial for our environment and our health because it is grown in fertile landfields that are free of harmful 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. It is composed of 30% natural rubber and 70% synthetic rubber.

Both natural and synthetic rubber have a high tear resistance, good low temperature flexibility, and high tensile strength. This mix allows maximum performance and comfort. 


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.


Packaging is the leading contributor to pollution, specifically in marine environments. Petroleum-based plastics only exacerbate this pollution problem and have a profound effect on the environment and wildlife that lives there.

In an effort to reduce our environmental impact, we've decided to avoid plastic bags. Instead, we are using biodegradable mailer bags made from corn starch (for every single order). When exposed to light, air, moisture and microbes, our bio-bags break down to natural elements that are found in nature.

Plastic-free packaging, while laborious to produce, is a step in the right direction for minimizing the amount of petroleum-based plastics that end up in landfill.
