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.

The Nike Cortez is the first track shoe released by Nike in 1972, and is therefore thought to be a significant aspect to the success of the company. The Nike Cortez was first designed by Nike co-founder Bill Bowerman, aiming to produce a comfortable and durable running shoe for distance training and road running.

Founded by Bill Bowerman and Phil Knight on January 25 1964, as Blue Ribbon Sports, the company became officially Nike, Inc. on May 30 1971. The company was named after the Greek goddess of victory, Nike (Νίκη).

On Nike tags it is the production date, usually a few months before the shoe was released for sale.
