I agree that better lighting will make it easier to tell real from fake but my gut says fake because the soles are too clear, left leg of the jumpman looks broken, and the pointy shark teeth.
I think the sulfurs got pulled to get relocated at outlets or places where they were selling better. They were sitting around everywhere here then mysteriously vanished one day
I think each year nike makes one of their sig models more limited than the others. Happened with the KD 4 last year, kobes this year. Even though they're not as limited as the kd's were last year, they're still appearing at stores in much smaller quantities than the other shoes.
Yes, you will specify size in the dm you send to them as well. Nike recently changed their automated system so that if you receive a dm back it no longer tells you what size you reserved (no idea why), but assuming you only send one dm, thats the size they write you down for
