Correct stitching, correctly colored soles, metallic gold Jumpman symbol on the back, feathers looked etched, 3M = legit.
I'd still do some more research though...just recently have we started seeing GM DB3s start to pop up on the market, so these (and the DBX's and Vs) could be next. Unless there's been an "new release" on the GM front, the pair photoed are legit.
