Technical and material developments have been at the core of adidas’ running shoe DNA since the beginning. Innovations such as the ZX heel counter and the Torsion bar cut-out had just as much impact on street style as they did on the track, especially in the ‘90s. There are echoes of that era throughout the adidas Originals spring/summer 2013 collection, with bright neon and block colours showing up across iconic silhouettes such as ZX500, Phantom and Torsion Allegra.
