adidas’ City Series is all about celebrating casual sneakers from the archives and their namesake locations around the world. This time, it’s Barcelona’s turn, and the shoe is just as clean-cut and retro as you’d expect. It’s based on the smooth tongue, early ‘80s version, with the same crisp white leather, suede overlays and blue accents across the uppers. An off-white sole unit — inspired by another casual icon, the Trimm Trab — completes the look.
