Lighter. That's all Eric Avar could think about. How can I make a lighter performance basketball shoe? Today's portion of "20 Designs That Changed The Game" examines how Avar went about designing the Nike Air Hyperflight. Borrowing from elements featured on track spikes, the shoe was built from the ground up with weight as the focal point. No unnecessary technology was added. It was as close to the sock as you could get. The Hyperflight was ultra-thin, but still managed to offer the end-user a great deal of support. Combined with vibrant colorways, the shoe became a turning point in basketball footwear development. [via Nike, Inc.]
