The Nike EXP X-14 sneaker, a shortened form of the word 'experiment', draws inspiration from Nike's previous running shoe designs and incorporates modern technological elements. This sneaker, which debuted in June 2018, blends characteristics from the Nike Zoom Vaporfly Elite and Nike Zoom Drive sneakers. The 'Glacier Grey' iteration features a multi-layered textile and synthetic upper that highlights its Volt Flywire cables. Additionally, the medial side of the sneaker displays the number 'N3546', paying homage to the accomplished track star Steve Prefontaine's record-breaking mile time of 3 minutes and 54.6 seconds. Completing the overall style, the sneaker boasts a two-tone React foam cushioned sole for optimal comfort.
