On Ebay and many places there are fake shoes if you want to only buy the authentic types check this guide. 1st off is the hole count on the shoes. For low top air force ones the count should be this going from left to right. 2,3,4,5,6,5,4,3,2, For mid cut air force ones it should be 2,3,4,4,5,4,4,3,2 .For fake low tops the hole count is usually 2,2,3,4,3,2,2. And the same for mid tops.Next is to count the holes where you put the laces through it should be 8 on each side for low tops 9 for mid tops. Then on the label on the inside of the shoe where it says the shoe size it should always have a date printed on it somewhere. If there is no date on the shoe they are fake period no questions about it. Next where it says air on the side of the shoe where it goes -----AIR-------- squeeze around that area it should be somewhat hard.This is to test the materials if you can squeeze straight through it then it is made from cheap material and will rip in a week or so. Then on the tongue where it shows the nike sign and says nike air force one it should have 2 small r's next to the nike name and the nike check it should also say air force 1 on it. then on the inside of the label where it says Nike and the swoosh name are guaranteed on blah blah blah. it should go like that on fake ones it say these shoes are factory variants from blah. Also on the label where it says where the shoes are made it should only be made from these places Vietnam and China for white ones. Indonesia and China for black ones .And in some cases the multicolored ones are made made from Vietnam but mostly in china. Also nowadays most of the air force ones come with the new buckle check on the label on the inside it should have a 2007 date on the inside the fake ones have the new buckle but were made in years like 2005. Also if they came with the old buckles then check thew date it should not have a 2007 date. Also check the boxes of them usually they come in the new bow which is gray and says nike air on the top,
