Nike ZoomX Vaporfly Next% 4 - Running shoes | Free EU 。The Vaporfly 4 is a lean, mean, mile-eating machine. Nike® trimmed weight in the midsole, outsole and upper from the Vaporfly 3 without sacrificing performance. The result is a lighter, more propulsive all-around racing shoe that’s trusted from the mile to the marathon. WHAT’S NEW: A higher angle of the plate and lower heel-to-toe drop compared to the Vaporfly 3 give you an improved propulsive feel Upgraded Nike® ZoomX foam provides even more energy return than before thanks to a slight midsole reduction, giving you a bouncy, feathery feel Nike® reduced the weight of the outsole by using a thinner rubber compared to the Vaporfly 3, eliminating unnecessary thickness DESIGN: Engineered mesh offers improved comfort and a disappearing feel on your foot, reducing the weight of the shoe while supplying a more consistent fit The handwritten number on the midsole salutes the wear-testers who put these shoes through our rigorous test process to give you the best performance possible Reduced weight on the inside of the foot to give you a more stable ride IN-SHOE COMFORT: A full-length carbon fiber Flyplate provides a propulsive, racing feel ZoomX foam runs heel to toe to give you a springy, bouncy feel DURABILITY & TRACTION: Waffle outsole pattern with perforations saves weight and delivers multi-surface traction in various weather conditions
