Unless I am missing the point, production dates mean nothing. When I mean nothing, is when a shoe has a production date after the release date (2009 Spacejams) or more than the 6 months before release date. About most of the questionable pairs had production dates that are within range of legit production dates. This is when you need to a legit check (personally or have have a second or third opinion). That is why I am not too concerned with production dates because questionable pairs and legit pairs can have the same production date.
