The '80s vibe of ZX meets the '90s style of Torsion X. These era-hopping shoes are greater than the sum of their parts. The big Torsion label on the quilted tongue references the shoe's X-shaped stability bar. Up top, the mesh upper has soft suede details, plus a key ring of extra lace jewels that lets you customize your look. Underneath, energy-returning cushioning builds on adidas' running legacy.
