The term Quickstrike and the shortened "QS" version began showing up on boxes in the early 2000s. Back then, it was an unannounced release that hit the stores quickly and was in limited quantities. With the Internet giving us a look at sneaker rumors what seems to be years before they release, now it seems even a QS release gets can end up discounted on outlet shelves. (Or we could just be saying that so we can get our hands on them before you.)
