SteP (Sustainable Textile Production) by Oeko-Tex®
Trerè Innovation was among the first companies in Europe to obtain the SteP (Sustainable Textile Production) certification by Oeko-Tex®. This guarantees that all our textile processes for manufacturing socks, base layers and sportswear are sustainable. In May 2022, that certification was confirmed as a level 3 – the highest achievable.

Global Recycle Standard
From 2021, our products comply with the standards of the, the international organization that attests the use of yarns and fabrics coming from recycled materials and the respect of environmental and social criteria in all the production chain. This confirms our efforts towards a circular economy model based on sustainable production and consumption that promotes the reuse of materials.

Mission 2022: a “total green” supply chain
Our goal by 2022 is to help our suppliers meet the Oeko-Tex® standard so that they too will be awarded the Made in Green by Oeko-Tex® certification – an indicator of the utmost respect for the environment.
