Made in collaboration with the UK-based retailer, the Size? x adidas Superstar ‘City Series Tribute’ celebrates dual milestones: the 20th anniversary of Size? and the 50th anniversary of the Superstar. The sneaker’s white leather upper features patterns and colors corresponding with seven different cities — London, Buenos Aires, Berlin, Boston, Paris, Tokyo and New York — drawn from adidas’ 2005 City Series. 20/50 branding at the heel gives the nod to the joint anniversaries.
