The logo on the genuine AJ insole will fade over time.

Most of the LOGOs on the insoles of genuine NIKE and Adidas use glue printing technology. One of the characteristics of offset printing is that it is easy to fall off, coupled with the intense friction caused by feet moving and sweating. During the wearing process, friction between the feet and the insole will cause the print to fall off.

NIKE specially designed the LOGO on the insoles to prevent customers from over-trying on shoes.

The rise of Nike was in the late 1980s. At that time, Nike spent a lot of money to sign a contract with Michael Jordan, who had just joined the league, and spent a lot of money to pay a fine to let Jordan wear the red basketball shoes banned by the NBA at the time - Air Jordan 1 - for the whole season. As a result, the shoes became a big seller, and Nike became a leader in the sporting goods industry in one fell swoop. The leading brand has surpassed adidas.
