Totally agreed, QS label is a major concern. I won't take chances, OG colorway is my favorite shoe ever. Last retro sat big time but the culture is way different now
Good point about the QS, but I don't see these selling out... unless Nike made a super-small production run. The beasts will unlikely have any interest... more for the true Sampras/tennis fans... which is great.
Having said that... if you really want them, just get them for retail. The question you have to ask yourself is... if you like them enough, why take the risk? Is a potential discount worth the risk of not being able to get them?
