On the tongue in the original pairs from Nike There is the brand's logo. On the inside of the tongue on the tag should be product information, including size and country of manufacture. There is also a 9-digit serial number, which should correspond to the code on the box.

Heel shape The shape of the heel often deviates on fake pairs and this is one of the most important indicators for us. With fake Air Max 1s you often see that you can easily press the heel in, the bulge is missing and the part of the midsole also runs diagonally inward.

All authentic Nike shoes have a tag sewn into them with their size, barcode and model number on it. You will recognize it most easily by the barcode. Look for it inside: The tongue.

Nike product code If you want to check if a shirt is fake, Google the product code on the small inside label near the bottom of the shirt. The code you're looking for with Nike shirts is a 9 digit code made up of 6 digits, a dash and 3 digits.
