The Nike ZoomX Vaporfly Next% 2 is the next evolution of speed for reaching new goals and records from 10Ks to marathons.A revamped upper helps improve comfort and breathability, while the same responsive cushioning and secure support helps push you towards your personal best. Nike ZoomX foam delivers Nike Running's greatest energy return yet.A full-length carbon-fibre plate creates a responsive feel that keeps you moving through your stride. A redesigned upper uses mesh fabric placed in areas where you need breathability.The result is a softer, cooler design that contours to your foot. Reinforcement along the forefoot makes it extra durable and secure. An inner foam pod on the heel gives you extra cushioning. Light padding on the tongue helps reduce lace pressure at the top of your foot. The laces loop through lightweight side supports that eliminate the need for an arch band, which helps reduce weight. A wider toe area means a roomier fit. Grooves on the sole give you flexibility and multi-surface traction in a variety of weather conditions.
