The Adidas ZX 700 is a running shoe that was released in 1985, and replaced the ZX 500; which was released in the previous year. The ZX range of running shoes is still evolving - the most recent ZX shoe is the ZX Flux - and has been at the forefront of introducing Adidas running technologies; like the Torsion System.
The Adidas ZX 700 is now part of Adidas' heritage range of shoes (Originals) and is referred to as a "retro runner" by Adidas. While the ZX 700 is still suitable for road running, there are superior options available; that features cutting-edge Adidas running technologies like Boost. Therefore, the ZX 700 is viewed by Adidas as a shoe suitable for casualwear rather than for performance / sporting activities. The most notable feature of the ZX 700 is the extra large midsole cushioning: the midsole is an injection-moulded EVA midsole that provides excellent comfort for long-distance running, and is also lightweight. The upper of the ZX 700 is a combination of nylon mesh fabric and pigskin nubuck overlays; the nylon mesh makes the shoe lightweight, and the suede provides structure and durability. The outersole is a gum rubber that also includes a toe guard.
