Date: April 4, 2009

The Moment: On April 4, 2009, Nike released its first non-athlete collaboration shoe with rapper, producer, and trending style icon Kanye West. Titled the "Air Yeezy," the shoe ran in a limited edition of 3,000 pairs, and retailed at a price of $215.

The Impact: The debut of the Air Yeezys was the most high-profile limited edition sneaker launch in the history of footwear. Lines started around stores selling it days before it went on sale, with people camping out to get their hands on a pair.

The Upshot: The Air Yeezy immediately became one of the most desired sneakers in the world, as did the second edition, with valuations for the Air Yeezy and the Air Yeezy 2 still exceeding over $2,000. Furthermore, it solidified Kanye West's place as one of the great contemporary fashion icons of our time, and one of the most influential people in rap both within and aside from record sales.
