Simple and stylish, the ZX Flux is a descendent of the iconic ZX 8000 running shoe. It has a one-piece nylon sock upper with mesh featuring velcro stripe and welded TPU 3-Stipes. The lightweight shoe has a TPU heel cage, midsole and outsole that echo the iconic ZX thousands series. The uppers are little bit higher than in ordinary Flux models. Additional blue laces included.
