The suede is made from the underside of cowhide, previously brushed to make it softer and more flexible. It comes from farms in southern Brazil (Rio Grande do Sul). It is tanned in Brazil, without using dangerous or prohibited chemicals. VEJA uses conventional dyes that comply with regulations. Special attention is paid to the use of water during the tanning process. Additionally, the suede is coated with PFC-free (chemical compound) water-repellent oils to protect the shoes from light rain. The suede is Silver certified by the Leather Working Group.
