A buyer paid resale for a pair of Air Force 1s, white, the most common sneaker on the planet. They arrived, and they looked right: the leather, the swoosh, the sole, the laces. Then she checked the style code, and it did not match anything Nike had ever made. The shoes were fake, and the fakes were good enough that the only thing wrong with them was a six-character code on a tag inside the tongue. The code is the check that matters most, and it is the check most buyers skip.
Resale sneakers are the most counterfeited product on the internet, and the fakes improve every year. The leather gets better, the stitching gets straighter, the box gets more convincing. The checks that still work are the ones that depend on information, not on appearance: the style code, the stitching pattern, and the smell. They work before you pay, if you ask for them, and they work after the shoes arrive, if you know where to look.
Every Nike shoe has a style code, in the format of six characters, a dash, and three more: xxxxxx-xxx. The code identifies the exact model and colorway, and it has to agree in three places: on the box label, on the size tag inside the shoe, and in the listing. If the three do not match, the shoes are fake, whatever else looks right.
The codes are public, and they are easy to check. A white Air Force 1 '07 is CW2288-111. The black version is CW2288-001. A Jordan 1 High OG Black Toe is 555088-061. Look up the code for the shoe you are buying before you buy it, and ask the seller for a photo of the size tag and the box label. A seller who will not show the code is a seller who knows what the code says.
Genuine stitching is straight, even, and consistent in its distance from the edge. The stitch count is the same on the left shoe and the right shoe, and the stitching follows the shape of the panel without wandering. Fake stitching is usually close, and close is where it fails: a stitch that drifts, a line that is not parallel to the edge, a count that differs between the two shoes. Compare the left and the right, stitch by stitch, and the difference will show.
The glue is part of the same check. Genuine shoes are assembled cleanly, with no excess glue visible around the sole or the panels. Fake shoes often have glue stains, or a strong chemical smell, because the factory used more glue than it should have and did not clean it up. The smell is the quickest check of all: open the box, and if the chemical smell is strong enough to notice from a foot away, the shoes were not made in a Nike factory.
The box matters, and it does not settle the question. A genuine box has the right label, the right style code, the right size, and the right barcode, and the printing is crisp. A fake box is usually close, with a label that is slightly off, a barcode that does not scan, or a color that is slightly wrong. But boxes get swapped. A genuine pair can arrive in a fake box, and a fake pair can arrive in a genuine box, because the box is the easiest part to copy and the easiest part to swap. Treat the box as evidence, not as a verdict.
The UV test is the last check, and it is the one that surprises people. A UV light can show factory guide marks on genuine shoes, faint lines that the factory used to align the panels, which are invisible in normal light. Fake shoes usually do not have them, because the counterfeit factory did not know they were there. A cheap UV flashlight is a better authentication tool than a magnifying glass, and it fits in a pocket.
Ask for the photos before you pay: the style code on the box and the tag, the stitching on both shoes, and the sole. A seller who sends them is a seller who has nothing to hide. A seller who refuses, or sends stock photos, has already told you what you need to know.

Every Nike shoe has a style code in the format xxxxxx-xxx, like CW2288-111 for a white Air Force 1 '07 or 555088-061 for a Jordan 1 High OG Black Toe. The code has to agree on the box label, the size tag inside the shoe, and the listing. If the three do not match, the shoes are fake.
Genuine stitching is straight, even, and consistent in its distance from the edge, with the same stitch count on the left shoe and the right shoe. Fake stitching drifts, is not parallel to the edge, or differs between the two shoes. Compare the left and the right, stitch by stitch.
Often, yes. Fake shoes frequently have a strong chemical or glue smell, because the factory used excess glue and did not clean it up. Genuine shoes are assembled cleanly with no visible glue. Open the box, and if the smell is strong from a foot away, that is a warning.
No. Boxes get swapped, so a genuine pair can arrive in a fake box and a fake pair in a genuine box. Treat the box as evidence, not a verdict. The style code, the stitching, and the UV test, which can show factory guide marks invisible in normal light, are the stronger checks.
