The adidas ZX line debuted in the 1980s with the purpose of creating a shoe for every type of runner. Building off of the ZX 600 from 1985, this bright Fresh Green and Carbon ZX 630 features a breathable mesh upper with suede overlays. A TPU heel clip helps stabilize the design while cushioning is offered in the form of lightweight EVA foam. At the bottom, a grippy rubber outsole helps promote traction.
