Nike has worked with top-level marathoners in Kenya to develop the Nike Zoom X foam, which offers the best energy return ever achieved by Nike. It is placed directly under your foot for optimal responsiveness during your stride.
Flywire cables feature an incredibly strong cable system that pairs with laces to wrap the middle of your foot and arch for a comfortable, adjustable fit.
The transparent material on the upper is designed to give the impression that it moves even when it is still. She is also incredibly light.
The collar is narrower at the Achilles heel for optimal comfort over long distances.
A beveled heel and a rubber sole strip guarantee good reception conditions and smooth transition.
Rubber relief sections on the soleplate for added grip.
