KEEN creates adventure-ready footwear using contemporary and sustainable design techniques, like these black UNEEK sneakers, for example. The uppers are constructed using braided cord – which is made using recycled bottles – and breathable knitted textile, with openings at the sides to give the part sneaker, part sandal look and feel. Underneath, they come with EVA midsoles and footbeds to give superior, all-day long comfort.
