How to distinguish between true and false Nike sports First of all, in the field of sports shoes, you may know very little, very one-sided, and sometimes seem naive. First of all, I want to clarify a few concepts. 1。 Authentic shoes All the shoes that have been processed by the original factory and have original boxes, that is, the same goods as the specialty stores. 2。 The shoes in the factory are all processed and handled by the original factory, and there are no original boxes. 3。 The assembled shoes are made of raw materials, or waste materials, and processed in other private factories. 4。 Fake shoes are divided into worsted and low-proof, garbage materials and garbage work. 5。 A and B shoes A products can be equivalent to factory shoes in the sense, but some js confuse people and call the assembled products A products. Product B is a shoe with quality problems processed by the original factory. Mark the shoes with B and destroy them. Workers can also take it out, but the number is very small. It belongs to the pie level. What do you know about the shoes on your feet? Simply distinguish between true and false shoes, starting with the shoe logo. One. Each Nike shoe will be assigned a set of nine unique numbers. We can learn some information about these shoes from these nine figures. The arrangement of these nine numbers is the arrangement of the first six and the last three. The front and back groups are separated by a horizontal line, such as: 830142-101. The six figures in the front group and the back group are separated by a line, which can be divided into three parts: 8 30 2 18. Precoding after code: a number. Represents the attributes of wave shoes: 1, shoes for general sale, 2 (not adopted), 3 (not adopted), 4, model shoes for players, 5 (not adopted), 6, replica version or exclusive style of dusty shoe store, 7, customized version (to be determined), 8, 1997.
