as you may know.. nowadays 80% of nike air jordans sold on ebay are 100% fake....as you may or might not know their are many ways to recognize a fake. people will be using the term ''factory variants'' which means its a fake item. also all the jordans with the full size run are almost 99% fake.....jordans from the 1-21 series should usually have a buy it now listing of  at least 150 or more.when bidding ask the seller to take a pic of the tag inside the shoes and see the serial code at wwwdotair - jordandotnet everything will have to match to make it a 100 percent authentic air jordan item. also fakes usually have something wrong with toebox... they are usually squared up instead of being roundish....beware of the air jordan xi and vi.....two of the most longed for jordans....and the fake producers are smart racking up thousands of fakes based on those 2 models.. last thing always check this guys feedback....if he has at least 1 or 2 people commenting 100 percent authentic jordans,than he is a legit seller.......hope this helped..
