On March 18, 2017, adidas Consortium and Swiss sneaker boutique, Titolo, released the Titolo x NMD_XR1 Trail PK 'Celestial' sneaker. Titolo built a pop-up in Zurich, Switzerland to show off the sneaker's inspiration from Switzerland’s iconic mountain ranges. The XR1 ‘Celestial’ features an all-white upper with a translucent ice-blue outsole as a reference to the region’s deep-running glaciers.
