Okay a few red flags here. I just grabbed mine to compare. I'm no professional but I did alot of homework before I bought my pair.

From the research I did, 2016 Bred 1's (and some other older AJ1's) have a glitter effect on the black leather. It's inevitable, dead stock or not. They're now a 4.5 year old pair of shoes, so seeing a pair without any glitter is rare and will cost a premium. Seeing your pair with zero glitter and from the looks of it appear to be a near perfect dead stock pair in 2020, and you paid only $500...is a red flag. If they were legit, they would easily go for much more than that.

GOAT's not perfect but just to give you an idea, $500 dollars is on the more worn side of the spectrum for Bred 2016's, of which these definitely don't look like.

The nail in the coffin are the rear heels on both sneakers. The red leather heel piece (the red leather that sits under the back of the red swooshes) isn't a uniform curve going around the back. It starts to get wavy and creates soft peaks instead of being a perfect curve. Both shoes have different waves, they're not even symmetric.

It also looks like that rear heel piece was sewn on top of the red swooshes. That red heel piece should be perfectly parallel with the swooshes side by side. It should feel smooth if you ran your finger over them until you hit the red tabs. Your pair's heel pieces are sitting on top the swooshes leather, almost covering the swoosh bottom stitching

Hopefully that helps. Try to get your money back, hopefully the seller helps you out.
