I'm pretty sure they sometimes use that box tag for PEs/samples made for athletes. My boy works for the Eagles and occasionally gets some shoes that were sent to players and they have that tag on the box.
The real, release version of the shoes have a matte finish. Those seem to have a glossy finish. Or maybe it's just the lighting.
I'm not sure there's really a market for these to be faked, which is why I'm leaning more towards samples .
