The ZX Flux made its entrance on the scene in the 1980s. To give the model a modern update, adidas released the ZX Flux 'Triple Black' in 2015, with a one-piece black mesh upper that includes a welded TPU cage on the Three-Stripes branding. The runner also boasts a TPU heel counter for added support and a ZX 8000 midsole with a TORSION midfoot bar for an extra secure fit.
