First of all, I hope friends who have questions will understand one thing: the concepts of A and B products are different from the concepts of factory, genuine, sold and fake. These are two different classifications but there are *** same place. Many explanations cross-explain them, which confuses some friends. The reason will be mentioned later. Let me tell you my opinion, hope it is easy to understand the whole story. 1. Products A and B -------- In terms of quality (it only means quality) The original source of the term A and B is the classification of quality testing, which is just a division of quality. Product A means "shoes made by authorized factories according to strict process control and passed formal testing". The only difference between product A and genuine products is that "product A is genuine before being sold. Once product A is listed on the regular sales channels, it is genuine." ”. These foreign shoe companies do not have their own shoe factories. They rely on certification to authorize shoe factories to produce shoes, and then inspectors verify that they are qualified and distribute them to various sales channels. These are A products. Those that fail the quality inspection will be marked with a red B mark and then destroyed centrally. So B means the quality is not up to par. The so-called B products generally have a B mark during formal testing (but special leakage is not excluded). The trick is that during partial testing or destruction, internal staff smuggle out B products and circulate them underground to the market. In fact, they are selling shoes with substandard quality. Another situation is that the inspectors mark some shoes (A products) that pass the quality standard without authorization with the B mark or mix them together, so that they can be smuggled out easily. There is actually no quality problem with this shoe. Note: 1. JS developers in the market deliberately expand and confuse the concepts of A and B. They often call non-original A products, which is just bastard talk! If they are not made by a designated shoe factory, they are still qualified to be called A products. Who rated this A grade as 2? Taking advantage of the above-mentioned tricks of B products, they deliberately and mysteriously said that some fake/defective shoes are stolen B products. , also said the quality is the same as product A. 3. Since A-grade shoes do not have their own obvious markings, some people will claim that the stolen shoes in question or fake shoes are A-grade shoes. 4. Whether it is product A or product B, as long as it does not come from regular sales channels, it is illegal and not genuine! ! Even if the quality is the same as the original product! ! 2. Factory shoes, authentic ones ----------- Based on the source, there was no concept of factory shoes. This idea was spread by well-informed people in the early days. All "shoes that flow out from designated authorized shoe factories through informal channels are called factory shoes", which includes A and B products. Including stolen product A; stolen product B; stolen product that is named B but actually is product A; stolen defective products. Please remember that only products that are truly authorized by the original manufacturer are factory shoes. The so-called "branch factory" factory shoes sold by some JS on the market are completely deceptive! Genuine products are the most strictly completed products and can only be purchased through regular agents and channels. Of course, the price is also the official price, so it is a bit expensive. Genuine product means "product A sold through regular channels and at regular prices." Identify genuine products: Except for discounted prices, the prices of genuine products are all national uniform prices specified by the company; except for regular channels and formal agents (including some small shop setters), other products are not genuine. Genuine products must come with original shoe boxes, have warranty documents, and must have formal quality inspection marks. It can be seen that the concept of authenticity is not only about quality, but also includes price, sales, brand and other aspects. So now there are often people claiming that genuine products are leaked from the original factory. They are either deliberately confusing the concepts of smuggled products and genuine products, or they are just talking in their sleep. What is especially hateful is that there are people who claim to be genuine products that are not produced by the original factory to defraud money. 3. Fake shoes and fake shoes -------------- From the production point of view, fake shoes are a type of fake shoes! ! Don't presume that so-called original materials can be used to make XX memorial arches. Shoemaking is to use excess materials produced in designated shoe factories, stolen materials, unqualified materials (the materials are also selected and tested), rags picked up from the factory's waste, etc., and then hide in a corner by yourself Shoes made with lowly tools. Please note here that some of the stitched shoes look very real, so many people pass them off as factory shoes. Note: 1. People with common sense know that shoes are a complete process. If you use some so-called original materials (such as air cushions) and call them good quality, it is basically an aircraft carrier glued with 502. You will deceive yourself and others. .

And it can be said with certainty that the so-called shoemaking only uses a few raw materials, and the components are not matching (for example, 42 soles match 41 uppers). (Of course, there are also strong people who can steal the whole set of parts and divide the labor in detail. I have nothing to say.) This is the reason why it is easy to tell the difference between shoes by looking at the shoe label. 2. Shoes are still fake. Nowadays, the price seems to be higher when the shoes are made of original materials. Everyone will know what they are after reading the above. Illegally stolen materials, informal assembly, informal sales channels, poor quality, these are not fake shoes, they are prostitutes in the red light district, or they are not chickens. They are completely fake shoes: they are copied by themselves. Everyone knows what they are. . (However, fake shoes are also divided into grades) Nike\Adidas Authenticity identification method First of all, how to analyze the number of NIKE shoes. 1. The numbering rules of shoes before 2001 and a few 2002 shoes. Let me first introduce the schematic diagram. The picture shows AIR FLIGHTHPOSITE KG produced in 2000. Please pay attention to the horizontal line in the picture: ①: Place of production, MADE IN TAIWAN represents production in Taiwan, but interestingly, most of NIKE’s shoe boxes are American goods from MADE IN USA. . ②: Production date, "000911" represents production from September to November 2000. ③: Production factory number, "PC8" is NIKE's factory in Taiwan, where most sample and position shoes are produced. ④: Shoe size. ⑤: This is the 9-digit item number we will mainly introduce! The 9-digit item number in the picture is 830196-002. We need to divide it into three sections, namely 830 (first code), 196 (second code), and 002 (third code). I will explain them one by one below. The number in the first code represents the series function category of the shoe. The meanings of these three numbers are as follows: [i:35925bc72c] The first number at the beginning means: [/i:35925bc72c] If it is "1" means: shoes that are generally on the market. Most of the early shoes used this. If it is "4" it means: player version of SAMPLE shoes. If it is "6", it means: a replica or a style or color sold exclusively by a chain shoe store. If it is "7" it means: customized shoes. If it is "8", it means: shoes that are generally on the market and were launched in 1997. If it is "9", it means: limited edition for a certain country or region. In addition, the upper definition of numbers 2, 3, and 5.

The two numbers after [i:35925bc72c] are used to determine the series, as follows: [/i:35925bc72c] 02: Men's indoor jogging shoes 03: Women's indoor jogging shoes 04: Men's jogging shoes 05: Women's jogging shoes 06: Unisex running shoes 07: Country running shoes 09: Men's jogging shoes 10: Men's and women's beach slippers 13: Rugby shoes 15: Metal spike-soled baseball shoes 16: American football shoes (removable) 17: Men's, women's and children's beach slippers 18: Wrestling shoes 21: American football shoes (multifunctional) 22: Men's ACG skateboard shoes 30: Men's basketball shoes 31: Women's basketball shoes 32: Baby basketball shoes 34: JORDAN series (young children) 35: JORDAN series (teenagers) 36: JORDAN series 37: Women's basketball shoes 38: Women's ACG water sports shoes 40: Men's tennis shoes 41: Women's tennis shoes 42: Men's tennis shoes (retro) 43: Women's tennis shoes (retro) 44: Men's volleyball shoes 48: Women ACG shoes 50: Baby shoes (not classified) 51: Boys' shoes (not classified) 52: Girls' shoes (not classified) 53: Boys' shoes (not classified) 54: Girls' shoes (not classified) 58: Women's volleyball shoes 65: Men's ACG boots 70: Men's multifunctional shoes 71: Women's multifunctional shoes 72: Women's cheerleading shoes 73: Men's multifunctional training shoes 74: Women's multifunctional training shoes 75: Men's ACG shoes 78: Weight training shoes 80: Men's tennis shoes 82 : Men's walking shoes 83: Men's golf shoes 84: Men's ACG cycling shoes 85: Men's ACG shoes 90: Men's ACG water sports shoes 91: Women's walking shoes 92: Women's golf shoes According to this judgment, the first code of 830196-002 What it represents is: (8) Shoes generally available on the market (30) Men’s basketball shoes. It should be clear at this glance that it is a men's basketball shoe that is normally on the market. The second code is 196. The meaning of these three numbers is not important. It is just a serial number, which means which shoe is on sale in this category. So we add up the first and second numbers to judge. 830196 means: This is a men's basketball shoe that is generally on the market, and it is the 218th design style. It’s easy to understand! The third code, which is the last three numbers (002), represents the color number of the shoe, as follows: 0: Black/Grey/Silver 1: White 2: Brown/Champagne 3: Green 4: Blue 5: Purple 6: Red 7: Yellow/Gold 8: Orange 9: Gold (metallic) However, regarding the coding of gold, we have never been able to figure out when "7" is used and when it is not. Can you use "9"? I feel that "9" is usually used if the gold color is heavier and has a metallic texture, such as Posite training. As for the further division of these three numbers, few people have studied it, and most of the FANS who have studied it have different opinions. Here I draw on some people’s experience and conduct a series of verifications to give a closer explanation. Of course, none of this is 100% correct, but for the time being, I think it can be said to be 70% or 80% sure. It is for reference only: The first number: refers to the color of the shoe upper. It is worth noting that it is not necessarily that The main color accounts for the most proportion, and many of them are determined by the color of the shoe upper. For example, the 002 we are talking about starts with 0, which represents black. The second number: usually the color used for the Nike Logo. Of course, for the Jordan series that does not have a Nike Logo, the color of the Jumpman logo will be used. Or for example, the 002 we are talking about starts with 0, which represents the black Nike Logo. Another example, the red and white AJ11 LOW is 161, but the red and white BB4 is 101. The reason for the different color numbers is that the former is 161 because the Jumpman logo is red, but the Nike Logo in BB4 is silver, and the upper is white, so the color number is 101. The third number: This is usually used to distinguish when the first two digits are the same in the same shoe model.

For example, Air Presto (104231) is divided into 001 (black and yellow), 003 (grey and orange), 004 (black and silver), 005 (black and blue), 006 (grey and purple and black) and 007 (all black). In addition, when there are more than ten colors of a certain combination, the first number may be "9", such as AF1, "11x" and "119", there will be numbers such as 910, 911, 912, etc. Let’s get back to the point. Let’s put these three codes together and it will be the main color used in this shoe. The third code in the example is 002. The color of the watch is black upper, black Nike Logo, and black face. The second shoe in the hook color scheme. 2. The numbering rules for most shoe models after 2002. Let’s first introduce the schematic diagram. The picture shows SHOX SUPREMACY produced in 2002. Please pay attention to the horizontal line in the picture: ①: Origin, MADE IN CHINA represents production in China. ②: Production date, "021202" represents production from December 2002 to February of the next year. ③: Production factory number, "LN3" seems to be NIKE's factory in Fujian, the full name is "Fujian Dafeng Group Co., Ltd.". For information about this, check out RAVEN’s previous posts, which have more detailed descriptions of shoe boxes and factory locations. ④: Shoe size. ⑤: This is the 9-digit item number we will mainly introduce! The 9-digit item number in the picture is 305522-101. We need to divide it into two sections, namely 305522 (the first code) and 101 (the second code). I will explain them one by one below. The number in the first code no longer represents the series function category of the shoe in the new numbering system. It is only used as an ID number for system identification. The first number of all shoe styles is represented by "3". As for the following five digits, it indicates which product is under the new labeling rules. The larger the number, the later the launch time. However, there is still something to note. The number of the first pair of shoes under the new numbering rules is "02001", not "00001". This is still helpful for everyone to identify fake shoes. In the final chapter, I will introduce how to use numbers to identify fake shoes. The number in the second code represents the information of the shoe color. The specific rules are the same as the original ones. Please refer to the article above. I will only briefly summarize it here: The color comparison table is as follows: 0: black/grey/silver, 1: white, 2: brown/champagne, 3: green, 4: blue, 5: purple, 6: red, 7: Yellow/gold, 8: orange, 9: gold (metallic). The rules of happiness are as follows: the first number represents the color of the shoe upper; the second number represents the color of the logo; the third number is usually used to distinguish the same style of shoes with the same first two digits. To sum up, the meaning of 305522-101 is: under the new numbering rules, the shoe with ID number 05522 has a white upper and silver Nike Logo. It is also the first shoe of this shoe to be available in white and silver hook color. The use of numbering rules to identify fake shoes has always been one of the most direct and effective ways. Although not all fake shoes are wrong, it is certain that shoes with wrong numbers are definitely fake. I will give an example below to introduce how to use this method. The picture in the picture is a very similar-looking Aj16 assembled shoe. Of course, I have specially modified one place in order to distinguish it. Friends who are familiar with it should easily spot this. But for those who have never seen Aj16, it was really made perfectly before I modified it. It is impossible to tell from the appearance. Even if it is said to be a factory shoe, it will be believed. In this regard, even if we have never seen the real shoes and do not know the correct item number, we can easily debunk it just by identifying them based on the numbering rules. Let's take a look. The item number of this shoe is "830222-101", so there are two mistakes in it: First, the first three digits of the Jordan series basketball shoes should be "836" or "136"! So this pair is fake! The second point is the color code. How could the black patent leather toe begin with the word "1"? You can also know the color code that should be "0xx" just by guessing. If there is a schematic reference, black upper and red LOGO, then the color code can be determined to be "061". So this pair is fake!
