With the ZX 500 Boost, adidas mines its 80s archive to resurrect a vintage runner using 21st-century technology. The hybrid silhouette takes the upper of the ZX 500 runner – finished in the OG grey and red colorway – and updates it with engineered mesh at the toe box and fused three-stripes on the synthetic quarter panel. It's then placed on a full-length Boost midsole in a crisp white shade, replacing the traditional EVA foam of the original.
