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.

“SE” stands for “Special Edition.” A shoe or sneaker labeled “SE” is especially rare and hard to come by. Special Edition footwear is unique and only released in small quantities. Typically, these shoes reflect a certain style, trend, event, or celebrity and are only available for a limited amount of time.
