The lightest Nike spikes for middle distance running ever created. They are perfect for track runs from 800 to 5000 meters. Thanks to the Flywire technology used, they are an innovation among spikes by achieving the maximum lightness of the structure, while maintaining the necessary protection for the foot and without compromising the durability of the shoe. The use of super-durable Flywire fibers allowed us to abandon synthetic layered structures or standard reinforcements in the heel area. This resulted in a shoe that perfectly fits the foot, which is the ideal solution for middle distance runners who want to achieve the best results on the track. Used by, among others, Alan Webb in the impressive 2007.UpperModern Flywire technology increases the durability of the shoe and gives the feet support exactly where it is needed. The foot does not move in the shoe, and the stability and fit during running achieved thanks to the incredibly low weight are a breakthrough in the design of athletics spikes.The use of airy, very light mesh ensures excellent foot ventilation and a feeling of comfort while running.MidsoleFlashlon foam formed as a result of a technologically advanced pressing process guarantees incredibly low weight, dynamic bounce and appropriate cushioning.OutsoleImproved Zoom Miler spike sole for even greater grip and comfort when developing high speeds on the treadmill.TPU Sharkskin used on 3/4 of the shoe length - a material modeled on shark skin, allows for a reduction in the shoe's weight, while providing excellent grip on various types of surfaces.Six replaceable screws are placed in optimally designated places on the sole to obtain maximum traction and rebound dynamics.
