The adidas ZX 4000 'White Lime' debuted in July 2019 as a fresh addition to the ZX line which began in the 80s with a performance-running focus. This edition dresses the shoe in three shades of white—Off White, Raw White and Chalk White—offset by black and lime-green details. The shoe's upper is made from mesh and suede, with EVA foam and a stabilizing Torsion System below for support. A rubber outsole helps improve grip from below.
