Back in June, Adidas revealed a shoe made almost entirely from recycled ocean waste. That product marked the beginning of a partnership between the sportswear firm and Parley, an organization trying to combat ocean pollution worldwide. Now, Adidas is taking this one step further: its new design features a 3D-printed midsole created out of recycled polyester and gillnets, a wall of netting typically used to catch fish. The shoe's upper part was manufactured with ocean plastic materials as well, Adidas says, making its concept footwear a complete eco-friendly package.
