The ZX line has always looked to the horizon — setting its sights on the next innovation in technology. That evolution never stopped, and today it looks like these juniors\' adidas shoes.

Made in part with recycled content generated from production waste, e.g., cutting scraps, and post-consumer household waste to avoid the larger environmental impact of producing virgin content. Lace closure. Mesh and neoprene upper with moulded TPU overlays. BOOST midsole. TPU heel counter.
