This sole is made using a GRS certified 100% recycled TPU mixed with additives and dyes for a weight of less than 10%.
The supply chain for the production of this sole is entirely traceable and guaranteed by the third-party control required by the GRS.

By using pre-consumer TPU waste selected upstream from production scraps we can make GRS certified soles with a recycled content nearing 100%* and completely recyclable:
Material weight: 300 gr. (100% recycled origin)
Weight of additives: 15 gr. (anti-static master)
Total weight: 315 gr. (of which 95% comes from recycled and GRS certified TPU)

* By convention, the GRS certification offered by Corplast for TPU products guarantees 90% certified recycled content (well over the 50% required by the certification standard), giving room to add masterbatch additives and fine tune the compound recipe (color correction, anti-static, anti-UV, grip, softness).

In case a master additive is not required, our products can be sold with a 100% recycled GRS certification.

According to the regulation issued by the TextileExchange, only GRS certified footwear manufacturers can make use of the GRS logo and advertising claims associated with the GRS certified finished “footwear” product.
Non-GRS certified footwear manufacturers can still take advantage of Corplast’s GRS certification to promote the sustainability of their products in relation to the individual components used.
Many physical or e-commerce marketplaces are already applying smart labeling that takes into account the recycled and certified content of relevant components such as soles, insoles or uppers.
