The difference is that most of the raffles done for these are pretty legit (Adidas with the ipad raffle entry), so not a lot of shady business practice by managers who aren't being watched when conducting circus raffle tickets. Same thing with the 750 Boost release, even though FTL, FA, Champs carried these for the 750, the sale of the shoes were heavily controlled by Adidas representatives INSIDE those footlockers to make sure they aren't backdooring or selling to employees.
And like another member said, yeah this is much more widely available than the 750 Boost because of so many stores getting them, but they are still limited in a sense because most stores got 1-2 FSR. And lets not forget that Adidas did scrap majority of the 750 release, so who knows how many pairs of 750 Boost are in limbo. But I'm sure Kanye definitely voiced his opinions to make the 350 more available as production were probably cheaper for these than the 750.
but you didn't win both pairs though right? Didn't you have a plug or paid resale for these?
