Better materials, smaller footprint
Bio leather
Bio leather is a remarkable material which is the result of years of R&D by our partners. There are no metals or nasties in it. It is tanned using the extracts from Acacia and Mimosa trees and is as kind to the earth as it is to your feet. The colour palette is made from natural dyes that fade with time and give the shoes a natural appeal.
This incredible leather achieves an impressive 100% decompostibility in less than 30 days. Bio leather is locally produced by our partners in our Portuguese city of Ovar.
Burel
Made from 100% sheep's wool on ancestral looms, it boasts high tensile strength, resisting breakage, pressure, and light exposure. This premium material sustains a cozy environment, insulating against heat and cold, while its fast-drying, dirt-repellent nature ensures enduring charm in any setting. With a remarkable water resistance of 98.5%, Burel absorbs moisture efficiently, drying quickly and effortlessly.
Eco cotton
We only use cotton sourced from trusted partners in the Better Cotton Initiative. This is a remarkable collaboration of forward-thinking individuals and organisations committed to making a positive impact on our planet. They work closely with cotton farmers to promote sustainable farming practices, and ensure that any cotton with their endorsement is grown in a planet positive way.
Our commitment to sustainability extends even to the dyes we use. Our beautiful colour palette is the result of extensive research and all dyes are compliant with the OEKO-TEX STANDARD 100, a trusted industry standard for sustainability.
Tencel
Our knitted styles are made with Tencel. This is a superhero fibre which has blazed a trail in environmentally savvy product development.
It is made from wood, with a closed loop production process where waste and pollution are eliminated at every step. Tencel has high resource efficiency with a low environmental impact and truly puts nature first.
Rubber
Rubber is a renewable resource made from latex, the milky white sap that oozes from certain plants and trees when you cut into them. This process not only yields rubber but also ensures the preservation of the trees. Most of the natural rubber used in the world comes from the Hevea brasiliensis, also known as the rubber tree.
Our soles are made with expanded rubber, a material that is both natural and fully recyclable. 100% of every sole can be remoulded into a new one. Expanded rubber has remarkable advantages. It is lighter, more flexible and just as durable as non-expanded but the consumption of the raw material is reduced by a whopping 75%.
Certification
At a.li.ás we give priority to certified partners who share our values and commitment to sustainability.
We research the provenance of every component and we ensure that best practices are followed from factory to foot.
