What does ap on sports shoes mean?

Nike's color code usually consists of three codes, which refer to the three main colors on shoes. However, due to the change from R&D to sales, the colors appearing on the color code do not appear on the shoes, but there is not much difference, which can be used as a basis for judging the authenticity. The following is the reference color code comparison table 0 black 1 white 2 gray/brown 3 green 4 navy blue/blue 5 purple 6 red 7 yellow 8 orange 9 unknown abbreviation comparison table LN-xxxx- replica, shox basketball, Shox training QT- Qingdao-Running shoes QS- Qingdao-Running shoes XC- Guangzhou-Basic basketball shoes Y3- Dongguan-Advanced basketball shoes and training shoes FC-xxxx- Sandals and outdoor shoes SF- Shenzhen-Football shoes IR- Indonesia IP- Indonesia IW- Indonesia SF-xxxx- Football PC- Taiwan Province FT- abbreviation and actual representative draft SB=SKATEBOARD= skateboard AP. It is an Asian shoe board, LE stands for limited edition (limited edition), ND = new design (mostly referring to the use of new materials, such as patent leather and mesh ...) TB is a team's bulk, mainly to point out the color matching for the team to match the uniforms on the team. NU=NEW, which is mainly a new type of sneaker designed by JordanBrand with the original air jordan sneaker as the inspiration source. Retro = ReplicaQS = Quick Strike Ca = City Attack SP, which is represented by Nu retro, stands for Skate Professional. -Like Dunk dunk low pro Sp, it means that graffit or skate team geicrossover illustrates the relationship between Nike Dunk/AirForce One/AirJordan1. Nike dunks in Air Force One (1982). After air jordan 1( 1985), we can see that similar design elements appear on these three pairs of shoes. There is a saying that dunk is designed with air jordan 1 air cushion removed (which reminds people that AJKO is another product under similar planning). Later, with the continuous evolution of the times, various changes in materials and color matching were adopted, which is almost certain to be Nike's most color matching shoes. I believe it's hard to figure out how many dunks there are, not to mention some retro colors overlapping. This problem can be said to be none.
