The Classic Cortez QS 'Upside Down' from Stranger Things is a special edition of the iconic running shoe, featuring design elements inspired by the Starcourt Mall in the show's third season. Introduced in August 2019, a month after the season premiere, this shoe showcases a Bone outer layer that can be gradually worn away or burnt to unveil a hidden pattern underneath. The collaboration is reinforced by a co-branded tongue tag and sockliner, adorned with red text saying 'Suzie -- do you copy?' and sketched schematics of the show's main machine. Initially, this shoe was sold in unique packaging and came with limited edition pins.
