"The National Park Foundation and adidas have teamed up to release three different ZX models, as well as a pair of Adiletten. The ZX 9000 not only features Cool Granite, Dash Green and Chalk Solid Grey colours, but the upper is also made of rugged and weather-resistant CORDURA nylon. This material is visible throughout the base, its ripstop coloured in a light shade of grey to complement the much darker tongue, lining and branded heel pull. In addition, the sneaker features lighter leather and suede overlays that combine with the ""Dash Green"" sole to pay homage to Glacier National Park in Montana. The design is rounded off with a patch on the tongue."
