This 2016 collaboration between London brand Roundel and NikeLab, following their successful joint effort in 2013 to honor London's Underground transit system's 150th anniversary, gave birth to the Air Zoom Spiridon GPX x Roundel sneakers. Designed as a tribute to Transport for London's (TFL) iconic Johnston font and the vibrant 90s garage rave fashion, these sneakers feature a white upper adorned with an all-over print of the Johnson font, complemented by a translucent monofilament mesh overlay on the vamp. Other notable elements include an iridescent synthetic leather Swoosh, a fully reflective mudguard, signature 3M taping, and a white midsole equipped with Zoom Air cushioning.
