Your pairs are legit. Maybe it is a flaw, in which I have no idea. The footlocker pair is in the middle, the Champs pair on the left and the footaction pair to the right. The Champs and footaction pair has the "white" netting and the Footlocker pair has an "opague" netting. The perforations in the netting were diffrent from the footlocker pair compared to the Champs & footaction pairs. So it apprears 2/3 pairs look more like your backdoor pair.
As for your soles, the color is slightly different, which happens on practically all releases. That is not a big deal. It is possibility that it had to do with the environments that they were stored in the warehouse.
