I'm going through the same thing. I purchased a pair locally from a guy that says they came from overseas. Nike Hong Kong. No price tag on the box but everything else checks out about the shoes.
I purchased a pair of CNY 12's. I been canvassing YT looking at videos on real vs fake pairs. I'm skeptical. The box doesn't have the perforated price tag attached to the size tag. Everything else on the shoe checks out. They are laced up like retail pairs, and every other detail about the shoes...
