is very thin, and the Vectran fibers are only added where support is needed. Shoe weight can be reduced up to 50% through the use of Flywire. Track spikes (running shoes with spikes added for traction) containing Flywire are now lighter than Michael Johnson's famous Golden Shoes of the 1996 Summer Olympics in Atlanta, Georgia. These spikes are so light that athletes claim they are like "a second skin" or "spikes coming out of their feet." This is a goal that Bill Bowerman tried to achieve as co-founder of Nike and a spike designer. Shoes Many Nike shoes contain Flywire. These shoes are designed for a variety of activities and sports, including running, athletics, basketball, badminton, football, American Football, baseball and tennis. The athletics shoes were debuted at the 2007 World Championships at Osaka, while the rest made their first appearance at the 2008 Summer Olympics, in Beijing, China, though all are now available for consumer purchase.
