The Nike Vapor Superfly II has a revolutionary outsole that combines with Nike's Flywire engineering for utterly mind-blowing speed.
Flywire is High-tensile Vectran threads (stronger than Kevlar) which cut down on weight of the product yet adds stability.
Nike's Vapor Superfly II has an ultra-thin Teijin synthetic upper that has a ball-control coating and is lined with Flywire to deliver a precise fit and optimal support.
