adidas Never compromise on quality. These ZX 8000 Shoes don't. In fact, it's what they're driven by. Part of the adidas A-ZX series, a tribute to the first adidas running shoes, the minimalist shoes clearly stand for the letter Q with their luxe, mindful approach. In design partnership with Highsnobiety, they explore the notion of "Qualität," promoting a pure, calming aesthetic through cork and leather materials done up in earth tones.
