Nubuck is made from grain leather. The upper part of bovine skin has the thickest fibers, which make it soft, resistant, and highly qualitative. This part is grinded or scraped to give it a soft and velvety appearance. The Nubuck is also coated with water-repellent oils without PFCs (chemical compounds) to protect the sneakers from light rain.
The bovine ChromeFree leather is smooth and light. Coming from farms located in the south of Brazil (Rio Grande do Sul), it undergoes an innovative tanning process where no chrome, heavy metals or dangerous acids are involved. By simplifying the tanning process, the use of chemicals and energy is limited, the use of water is reduced by about 40% and the use of salt by 80%. After tanning, the water is recyclable.
