Crafted from chrome-free leather, this model features an embossed logo on the tongue, triple velcro closures, organic cotton laces and a white logo patch produced from rubber and rice waste. The mesh inner lining made from recycled materials was developed to acquire a better resistance to friction.

This leather 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.
