42. ZX 800
Year Introduced: 1986
Dropping in 1986, the ZX 800 represented the pinnacle of running performance. Decades later, the shoe was rehashed without stripes as a Beckham model. The OG featured a mix of Ghillie and Vario lacing for precise fit, and introduced the idea of reflective patches for night running too. Safety, when it comes to training, doesn't stop at securing the heel.
