Equipped with Torsion technology, the highly-technical ZX 8000 was added to the ZX line in 1988 and became an inspiration for future adidas shoes. Released in Summer 2011, the ZX 8000 Tech sneaker updates the classic with streamlined design. The upper is constructed of a synthetic nubuck upper, enhanced by breathable mesh underlays. The model’s signature heel clip and Torsion system stabilize the foot with each footfall.
