Boston-based brand Concepts partnered with Italian and Massachusetts-based brand Diadora to release a Euro-inspired colorway. The Concepts x N9000 'Lira' features a high-quality Moon Grey suede upper with mesh overlays and perforations on the toe box. The sneaker also boasts green, pink, blue, and yellow pastel accents throughout and “500000” Lira lettering on the heel side as a nod to the high denomination bill in Italy. Keep an eye out for custom printed insoles.
