Released on August 31, 2019 featuring the same color and materials as the original shoe, the ZX 9000 '30 Years of Torsion' is a retro runner with an eye on history. According to adidas tradition, the green colorway signifies the guidance performance element of running, and an updated lace jewel and interior detail honor Torsion technology. Connecting the shoe's heel and forefoot with a TPU arch, it provides support without sacrificing flexibility.
