The Nike ZoomX Vaporfly Next% 3 FK is designed for runners who want to get the most out of their training and competitions. Besides being a successful marathon shoe, the ZoomX Vaporfly Next% is also ideal for longer runs at a higher pace. Accelerate to victory with this competition shoe, designed for top performance during every race! Midsole This shoe feels lighter and more responsive thanks to the ZoomX foam midsole. While running, the foam provides support for all three phases of gait: Flexibility when your foot leaves the ground, softness when your foot moves forward and cushioning when your foot hits the ground. In addition, the midsole contains a carbon fiber plate known as the Flyplate, which acts like a spring. The shoe feels very responsive when walking because it propels you forward. Upper The upper of the shoe is made of Flyknit. This is a material that is based on a weaving technique and supports the necessary places. Outsole The rubber outsole has Nike's iconic waffle pattern that provides grip on dry and wet surfaces. Flex grooves provide extra flexibility in the forefoot to aid in a smooth walk. With the Nike ZoomX Vaporfly Next% 3 FK your performance will reach new heights and make you shine.
