Jordan 4's
These two different pairs of Jordan Bred 4's look really similar but the one on the left side is fake. The easiest way to tell if it's fake is to ha have two pairs next to each other. if you can't do that then the next best way is to look at the back flap, the lettering and Jordan sign, and the sole. The back flap on some are sometimes longer and more flabby than the authentic. Sometimes it's hard to see but the lettering and the Jordan symbol can sometimes be a little bit off. The font might be different and the Jordan sign might have fingers. Then the sole sometimes it's tiny details like the pattern of the traction.
Yeezys
Yeezys have a lot of fakes since they are really popular and don't sell a lot so people take advantage of this and sell fakes. The way to spot fake Yeezys is by the semi circle of cloth on it, the sole and the pattern of the colour way, The half circle is really easy to spot because the fakes look longer and wider than the originals. Another way is on the sole. On the sole they have a little padding on the middle of the sole that feels like a marshmallow and is really soft the fakes use plastic so it feels really hard. The colour way is also a way to tell if it's fake. On the turtle doves the colour of whit is a little darker, and if you look closer you can see that the black lines don't a line properly.
Jordan 11
Probably the most notorious shoe for being fake is the Jordan 11. The fakes look so much like the authentic that it is really hard to tell but the easiest ways to tell is by looking at the back of the shoe and on the sole. The back of the fake Jordan's the patent leather is closer to the 23 symbol and the back is wider than the authentics. The easiest way to check for fakes is by looking at the carbon fiber on the sole. On the carbon fiber on the real pair you can feel each square separately but on the fakes it feels like one full piece that is painted black and grey.
