The Alveomesh is a technical fabric made out exclusively of recycled polyester. It brings breathability, flexibility and lightness to the shoe. The suede is made from the underside of bovine leather previously brushed to make it softer and more flexible. It comes from farms in the south of Brazil (Rio Grande do Sul). It is tanned in Brazil, respecting the REACH norms. Special attention is paid to water usage during the tanning process. The suede is also coated with water-repellent oils without PFCs (chemical compounds) to protect the sneakers from light rain. *ethylene vinyl acetate
