The Hyperdunk is the future of basketball footwear. Constructed using Nike's 'Fly Wire" technology, Vectran fibers, which are five times stronger than steel and never lose their strength, are encased in the skim to harness the body of the shoe. These thin wires act as supports on a suspension bridge, providing the necessary support structure while eliminating excess weight above the sole.The sole is constructed with Lunar Foam, a material developed by NASA that gives the shoe excellent shock absorption and a great feel with minimal weight. With a breathable mesh tongue and a protective heel cup your safety and comfort is assured during your long flights.The sole is constructed with Lunar Foam, a material developed by NASA that gives the shoe excellent shock absorption and a great feel with minimal weight.
