• Extra padding at the tongue and collar helps keep your feet feeling comfortable. We also placed engineered mesh—which is stronger and more flexible than regular mesh—throughout the top for lightweight breathability. • Flywire technology is integrated with a midfoot band for total support that helps keep your feet in place. • Nike React technology is a lightweight, durable foam that delivers a smooth, responsive ride. We paired it with a Zoom Air unit at the forefoot and the heel for an energised feel. • The heel shape is designed to optimise landing, helping you easily transition from heel to toe. We've paired it with thick foam for a responsive ride. • Tongue is separated from the upper to give room for different foot shapes. • Waffle-inspired outsole gives you excellent traction. • Grooves on the rubber sole allow for natural motion.
