Nike SHOX R4 METALLIC Size: 28.0cm / US10 Color: White/Metallic Silver/Deep Royal Blue Unused, New With Box Metallic Silver and Royal Blue return to the streets! It all began in 1984. It was an idea held by the legendary designer Bruce Kilgore, who created immortal masterpieces such as the Air Force 1 and Air Jordan 1. Could he incorporate "spring coils" into the shoes to dramatically increase propulsion and rebound? From this groundbreaking idea, after about 16 years of research and trial and error, Nike's innovative cushioning technology, "SHOX," was launched into the sneaker scene in 2000 with a bang. High-rebound cylindrical columns are placed on the sole, and the shock-absorbing material "PEBAX" efficiently absorbs energy upon landing and converts it into powerful propulsion for the next step. This completely different approach from the "AIR" technology and the mechanical and futuristic visuals instantly captivated sneaker freaks around the world. The "SHOX R4," the running shoe that first featured the "SHOX" technology, is once again attracting attention. The biggest feature of the "SHOX R4" is the boldly placed four "SHOX" column structure. These work together to create a unique resilience, like a trampoline, and a one-of-a-kind "bouncing" feel. The upper design also strongly reflects the Y2K tech running aesthetic of the early 2000s. The streamlined silhouette combines glossy synthetic leather and breathable mesh panels, creating a futuristic atmosphere of the time.
