The main flaw of fakes of this shoe is the shape. More specifically, they miss the a bump in the heel. Fakes have that area too straight. See photos below for a better explanation.
The ankle lining of the shoe is of a different colour and material on the fake. It should be, just like in the picture, golden and nappy.
Highlighted is a wrong color for the blue stitching on the front and the back of the shoe. However, I also want you to pay attention to overall stitching and compare the pair you’re analyzing with a real one, make sure aren’t any inconsistencies.
The brown swoosh patch has a wrong shape on the fakes. Also pay attention to the placement of the golden swoosh and the stitching that’s outlining the patch.
