Short for ‘experiment,’ the Nike EXP X-14 sneaker takes design cues from Nike’s past running silhouettes and updates it with modern tech touches. It was released in June 2018 and combines elements of the Nike Zoom Vaporfly Elite and Nike Zoom Drive sneakers. The ‘Glacier Grey’ version sports a layered textile and synthetic upper that showcases its Volt Flywire cables, while ‘N3546’ printed on the medial side is a nod to track star icon Steve Prefontaine’s fastest mile (3:54.6 seconds). Underfoot, a two-tone React foam cushioned sole completes the style.
