Vince Carter's "dunk of death" during the United States' match-up against France at the 2000 Summer Olympics in Sydney made Carter an icon. But looking closer at his amazing play you will soon find Nike's own hero strapped to his feet, the Nike Shox BB4. Released in 2000, the Shox BB4 allowed, as designer Eric Avar put it, "technology itself to be the focal point." Long a hidden secret of the Nike footwear design team, the brand had to wait for sneaker technology to catch-up to find the right time and the right shoe to integrate a sole of this magnitude into. The shoe's design itself was inspired by a space-age concept that had Avar and his team looking at space suits, rocket boosters, and other astronaut gear for design details, building on the idea that you and the Shox could lift-off at any moment. A new generation of Nike's Shox technology still makes an appearance today, emphasizing the fact that solid design can easily stand the test of time.
