The Shox R4, which debuted in 2009, is the inaugural design from Nike's Shox series and draws inspiration from the resilient surface of Harvard University's indoor running track. This particular sneaker, known as the Nike Shox R4 'Dark Charcoal,' boasts a visually appealing two-toned upper complemented by perforated and paneled overlays. To infuse a vibrant touch, hints of green are added to the exterior. Enhancing performance, the shoe features four hollowed-out columns made of top-quality high-density PU foam, providing an exceptional bounce and effective impact control.
