16. Pump up or Air out.
Sneaker: Reebok The Pump
If the era of the "tech" basketball shoe began in the early '80s with the Air Force 1, it exploded in 1989 with the introduction of the Reebok Pump. The bloated hightop with the equally bloated pricetag intended to revolutionize fit, and if Reebok had to take the battle straight to Nike's doorstep, they certainly weren't going to shy away from it. Not everyone chose to "Pump Up And Air Out," but enough did that Nike introduced their own inflatable shoe not long after. And the fight was on.
