20. Foamposite One
Year Introduced: 1997
A molded foam shoe? The Nike Air Foamposite One remained a mystery until it hit shelves (or, for the observant, Mike Bibby's feet), at which point its $180 price point and space-age appearance created more questions than it did answers. What WAS that thing? Nike has never been afraid of new technology - or the cost it incurred - and the Foamposite One has since more than proved its worth through various descendants (the Foamposite Pro, Flightposite, etc.) and a whole rainbow's worth of colorways. And a full 15 years after its initial launch, it still looks like the future.
