Nike Joyride Duel Run Running Shoes--M 7.5/W 9

Nike Joyride Duel Run. I wore these twice. The White is hard to keep clean, but the uppers mostly look new. The soles got really dirty though. Please see last picture. Size Mens 7.5/Womens 9. Why Beads? "They’re soft, they’re bouncy, and they form the core of an innovative new cushioning system designed to help make all the ways you move feel easy—even running." A Softer Cushioning System "We spent years obsessing the beads—finding the right size, shape and feel to deliver a soft, comfortable ride. Here’s how it works: Every time you take a step—or stride—10,000+ beads shape around your foot to provide personalized cushioning and support, before responsively bouncing back to propel you forward." Absorbs the Impact "That soft ride doesn’t just go easy on your feet—it helps your whole body feel good. The Nike Joyride cushioning system offers 14% better impact absorption when compared to some of our most trusted running shoes."
