Every pair of real Nike shoes has an SKU (SKU (pronounced “skew”), short for Stock Keeping Number) that is identical to the SKU number on their box. If the numbers are missing or do not match, you may have a fake shoe. Check the tongue label.

Locate the tag inside your shoe. 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.

All Nike shoes are packed inside a box with a certain label and tag. The colour and print of the box usually vary depending on the style but mainly the boxes revolve around the colors red, orange, and brown. The print on the box should have the size, serial number, and style, with a barcode.
