First came the ZX Flux, and then models like the ZX 8000 Boost took adidas’ retro-inspired casual runner niche to another level. Now the modern ZX line gets a bold new addition for the ladies only, the ZX Zero Summer. Like its name suggests, the ZX Zero features a minimal, extremely light weight upper perfect for summer, constructed fully in neoprene with ovoid cut-outs. The sock-like upper sits atop the thin and streamlined adidas adiZero racing tooling. The unique new adidas ZX Zero is arriving now at select retailers globally.
