For this pair, sun-bleached colors nod to the past while modern technology lets you scan the QR code to find out more about the story behind how the shoes were created This shoe's upper is made with a technical yarn which contains at least 50% Parley Ocean Plastic — upcycled plastic waste, intercepted on remote islands, beaches, coastal communities and shorelines, preventing it from polluting our ocean. The other 50% of the yarn is recycled polyester.
