100% of our insole and outsole leather and 75% of our upper leather used in Peru is vegetable-tanned. This process uses tree bark instead of chromium and other harsh chemicals. Leather that is vegetable-tanned is more durable and reparable than synthetic alternatives, and is also biodegradable at the end of it's useful life.
The balance leather used is sourced from a local Colombian tannery which produces leather using an innovative "wet-white" tanning process. Like vegetable-tanning, wet-white tanning is chrome-free. It also uses 40% less water than conventional tanning and reduces the amount of toxins and minerals in wastewater by up to 80%, meaning wastewater can easily be recycled and reused in the production process.
Wet-white tanning is the first step towards a more sustainable future for traditional tanneries. They can use their existing equipment to produce with minimal additional financial investment.
