The adidas ZX line emerged in the 1980s, debuting designs that focused on improving the ride for runners of all types. Released in July 2019, the Wmns ZX 4000 'Clear White' features a mesh and suede upper with subtle Three-Stripes detailing on the sidewall. A neutral-based palette allows brilliant red-orange hits to stand out on the lace lock, eyelets, heel and outsole. The shoe is supported by a flexible foam midsole and Torsion System, finished with rubber tread.
