1. The material used in fake shoes will definitely be different from that used in real shoes, which is very important, because the real shoes are expensive, in addition to his own brand advertising and development expenses, the materials used in the shoes themselves are really expensive, which is absolutely not imitated. Generally, the developers of fake shoes will find materials with the same texture and attributes as those used in real shoes, but the grades are much worse to act as imitations. Material of real shoes

1. Upper material: NIKE usually uses artificial leather on basketball shoes and microfiber PU on running shoes. Although they are not genuine leather, they contain higher fiber density, better toughness and permeability than genuine leather, and are not easy to deform. Therefore, good artificial leather materials are more expensive and better than genuine leather. Generally, simulated shoes will not use superior artificial leather or microfiber PU to make shoes. The way to distinguish them is to look at the gloss material of the materials. Real shoes are shiny, and you can feel whether the upper leather is very tough and elastic by squeezing or stretching it by hand.

2. Some processes of the upper, such as hot-cutting micro-injection, are definitely made of TPU, while most fake shoes are made of PVC, which are the same in appearance, but the TPU material cost is high, and the flexibility and extensibility of the material are good, but PVC is not. Soft sex is not good, and it is easy to break when worn in winter

3. Shoe midsole: Although the overall appearance of the midsole is almost the same as that of the real shoe, there is still a gap in the material of the midsole. Although all the materials of the midsole are EVA secondary foaming materials (that is, we often say PHYLON), the hard and soft holiday shoes of the midsole are definitely different from the real shoes. Press the PHYLON with your fingers. You will feel moderate hardness and elasticity. After pressing hard with your nails, PHYLON will naturally return to the state before pressing, and will not leave the nails pressed for a long time, while the PHYLON of fake shoes will not reach the level of real shoes.

4. Shoe outsole: Although the outsole is made of rubber materials, the difference between real shoes and fake shoes can be seen. Real shoes will be mixed with some recycled chemical materials when firing the outsole. The purpose of this is to make the shoes more wear-resistant and slip-resistant, and the fake shoes will not take these into account when firing the outsole. Therefore, the anti-slip and wear-resistant degree of the outsole of the fake shoes is far worse than that of the real shoes. In terms of gloss, the outsole of the fake shoes is brighter than the color of the outsole of the real shoes, and another trick is to tell everyone that it will be very loud and crisp to wear real shoes and rub the ground with the forefoot on the plastic floor or floor. Cheep "sound and fake shoes will never have this sound under normal circumstances

5. The function of the sole: I want to talk about the problem of carbon fiber sheet and TPU support sheet as everyone said. When buying some cutting-edge products of NIKE, most shoemakers will look at the carbon fiber sheet of shoes to determine whether the shoes are real or not. This method can tell the truth of the shoes at a glance because the cost of carbon fiber sheet is really high, so fake shoes will not use carbon fiber sheet, but only look for it. Some materials similar to carbon fiber sheets will be used, which will of course make the truth and falsehood clear at a glance. Let's talk about TPU support sheets. Although the cost is not low, now there will be imitation shoes on basic big-name sports shoes. Of course, it will also be copied according to the order. In fact, it is also a trick to distinguish TPU. First, look at its color. The TPU of fake shoes is dirtier than the color of real shoes, and it is opaque in texture, and it is softer than the TPU of real shoes. < P > Second, real shoes and Fake shoes are also different in the shoe shape and some line directions.

Because the designers who make real shoes and those who make expensive shoes are different, the last and the version of shoes are definitely different from those of real shoes. Therefore, the shoe shape with real shoes is definitely different from that of fake shoes, and there are many differences between real shoes and fake shoes in some line directions of shoes because of the different versions opened by the designers.

Third, when making shoes. There are many differences between true and false in some details.

1. You can carefully observe the midsole of your shoes. There will definitely be several small dots protruding from the midsole. Although the dots are small, you will find out what these dots are for in a circle around the midsole. Why are there these dots? Because the midsole is to be burned in the mold, EVA is in a liquid state before burning, so we must first put these dots in a liquid state. The way to introduce these liquid EVA into the mold is to introduce the liquid into the mold through a very thin introduction pipe. The thinner the pipe, the smaller the bump left on the midsole after molding, so the developer definitely hopes that the smaller the dot, the better, so as not to affect the beauty of the midsole, but this is not to make it small. It requires a fairly high level of the factory to make fake shoes. Factories generally can't reach this level, so the protruding dots on the PHYLON midsole of fake shoes must be much more obvious than those on the PHYLON midsole of real shoes

2. Shoe sewing line: NIKE and other big brands also have quite strict requirements on the sewing line of shoes, and the length of each stitch should be even, and there should be no jumper. It is impossible for the work requirements of fake shoes to reach such a strict level

3. In the process of shoe forming, the shoe with the bottom attached is put on the last tree after the surface is turned first, so the bottom attachment is also the last process in shoe forming. Because the level of the workers who attach the bottom to the factory where the big brands are processed is very high, most of the shoes with the bottom attached are neat and the glue will not climb to the upper, which makes people feel very comfortable. If the soles are uneven or the glue climbs to the upper, the big brands usually will not check the fit. Generally, the lattice shoes will be sold to their own employees with B products, while the fake shoes will be sold out because they are not made of their own brands.
