LEXICON OF ECO-RESPONSIBLE MATERIALS

WHAT ARE OUR ECO-RESPONSIBLE MATERIALS?


VEGETABLE TANNED LEATHER

This is leather originally made from the skins of animals raised and slaughtered for food and produced by the process of vegetable tanning. This material then allows us to manufacture our vegetable tanned leather shoes with a lower impact on the environment.



RECYCLED RUBBER

It can come from all kinds of everyday products (used tires, industrial rubber, etc.). By using recycled rubber in the manufacture of our shoes, particularly in the manufacture of the soles of our eco-responsible sneakers. Thus, we give a second life to this material and we avoid environmental pollution.



RECYCLED POLYESTER

Polyester (plastic material) can be recycled from textile scraps but also from plastic bottles. Crushed and recycled, it is possible to recreate a fabric and thus be able to use it for the production of our eco-responsible canvas sneakers. By favoring this material, we participate in the protection of the oceans and more broadly, of the planet.



ORGANIC COTTON

Organic cotton is cotton that does not use any pesticides, insecticides or chemicals during its manufacture. There are different labels to identify and verify that the material is organic cotton (GOTS, OEKO-TEX). All our socks are made of organic cotton and made in France.
