The Shox R4 'Silver Racer Blue' was released May 2019 with a cool, ocean-inspired colorway to reimagine the icon in a rich summer motif. Originally created by Nike masters Bruce Kilgore and Sergio Lozano, the Shox R4 launched in 2000 accompanied by the famous 'Boing, Boing' ad campaign. Borrowing wavy and striated design lines from Lozano's contributions to the Air Max collection, the shoe combines Nike's running heritage with the springy feel of its four columns under the heel.
