To celebrate Nike’s ‘Breaking 2’ campaign—an innovative experiment to break the two-hour marathon barrier— Nike Racing created the NikeLab Zoom Fly SP 'Hong Kong' sneaker. Released in January 2018, this take sports a translucent, stretch-woven upper constructed from Flymesh with yellow Flywire cables. The predominantly white build highlights the race-inspired striping along its body, while a green digital stopwatch graphic on the heel references the marathon time barrier.
