Our Sneakers are made by:Bio Polyols Synthetic materials alternative to leather are usually oil-based. After two years of R&D, we discovered a way to instead employ “bio-polyols” - extracted from cereals - as raw material.● No fossil-derived raw materials● Less CO2 emissions● Less water-intensive production processOur BIO LEATHER uses this raw material, combined with viscose obtained from tree pulp, and recycled polyester textile obtained from recycled bottles.
