The Zoom Fly is a real speed demon, perfect for races up to half marathon distances, training at higher tempos and intervals. Designed to increase your speed, stability and confidence during every race. Go for gold with this competition shoe! Midsole The ZoomX foam midsole makes the shoe feel lighter and responsive. The shape of the foam offers you support for the three phases of acceleration while running. Flexibility when your foot lifts off the ground, a smooth experience when your foot moves forward and cushioning when the foot hits the ground. The midsole also contains a Flyplate, also called a Carbon Fiber plate. This plate works like a kind of spring. It propels you forward as you walk and contributes to the very responsive feel of the shoes. Upper Zoom Fly's mesh upper keeps the shoe breathable and comfortable while running. Outsole Thanks to the rubber outsole, the shoe offers good grip and traction while running. The Nike Zoom Fly 5 will take your performance to new heights and make you shine.
