The '80s vibe of ZX meets the '90s style of Torsion X. These era-hopping shoes are greater than the sum of their parts. They build on adidas' running legacy by combining energy-returning cushioning with an X-shaped bar for extra stability. The mesh upper has soft suede details, and a big Torsion label stands out on the quilted tongue. A key ring of extra lace jewels lets you customise your look.
