Released in May 2019, the Shox R4 'Silver Racer Blue' presents a refreshing take on a classic silhouette by incorporating an ocean-inspired colorway that epitomizes the vibrant essence of summer. Crafted by the Nike visionary team of Bruce Kilgore and Sergio Lozano, the Shox R4 initially debuted in 2000, accompanied by the iconic 'Boing, Boing' advertising campaign. Drawing inspiration from Lozano's distinctive wavy and striated design elements showcased in the revered Air Max collection, this shoe seamlessly combines Nike's rich running heritage with the unparalleled springiness provided by its four columns positioned under the heel.
