Meet one of our most tested shoes. Whether you're tackling a 20-miler in the middle of marathon prep or stacking Tempo Runs together, this supportive design will help you feel cared for and sustained over the long haul. With higher foam and extra bounce, it's specifically designed to offset the wear and tear of your toughest training days. Responsive Ride Nike ZoomX foam is responsive and lightweight, giving you more bounce with every step. The foam is shaped like a rocker, providing support for the 3 phases of a runner's stride. It offers flexibility as you lift your foot off the ground, a smooth ride when your foot is moving forward and then cushioning at ground contact. Updated Comfort Higher foam creates an even softer feel, while a wide, exaggerated forefoot shape offers a more stable ride. Evolved Stability An advanced Flyknit upper provides breathability in areas where your foot heats up most. It uses strong, stretchy yarns to create a lightweight yet supportive feel with every mile. Celebrate the Swoosh The Swoosh logo celebrates its 50th anniversary by intertwining the past and present. The original Swoosh is outlined over the current version, representing the path Nike has taken from yesterday to today.
