The ZX Flux PK, inspired by adidas’ ZX runners from the 80s, is made with a breathable knit build and a sleek Triple Black colorway. Tonal welded TPU Three-Stripes provide textural contrast, as does the stitched-on suede heel cage. adidas’ Torsion system is embedded in the outsole for midfoot stability, while the compression-molded EVA midsole in matching black provides lightweight cushioning.
