1. Upper material: Nike usually uses artificial leather on basketball shoes and running shoes. Although it is not genuine leather, it contains higher fiber density, better toughness and permeability than genuine leather, and is not easy to deform. Therefore, a good artificial leather material is more expensive and better than genuine leather. Generally, high-grade artificial leather or superfine fiber PU will not be used to distinguish shoes. The method is to look at the gloss of the material, that is, the real shoes, squeeze or stretch by hand, and feel whether the upper leather is tough or not.
2. Some techniques of vamp, such as hot micro injection molding, must be TPU for real shoes and PVC for fake shoes. They have the same appearance, but TPU material has high cost, good flexibility and good ductility, while PVC is not. This material has no elasticity and softness, and it is easy to break in winter.
3. Shoe midsole: Although the overall appearance of the midsole is almost exactly the same as that of real shoes, there is still a gap in the material of the midsole. Although the material of the midsole is EVA secondary foaming material (that is, we often say PHYLON), the soft and hard holiday shoes of the midsole are definitely different from real shoes. The PHYLON of real shoes will feel soft and hard when touched with fingers, and will be very elastic when touched with nails. After pressing, the PHYLON will naturally return to the state before pressing, and will not leave nails for a long time, while the PHYLON of fake shoes can not reach the level of real shoes.
4. Shoe outsole: Although the outsole is made of rubber, the difference between real shoes and fake shoes can still be seen from the material of the outsole. When real shoes are fired at the outsole, some recycled chemical raw materials or carbon elements will be mixed. The purpose of this is to make the shoes more wear-resistant and anti-slip, and the fake shoes will not take these into account when firing the outsole, so the anti-slip and wear-resistance of the fake shoes will be far less than that of the real shoes. The outsole of fake shoes is brighter than that of real shoes, and another trick is to listen to the sound. Wearing real shoes will have a very loud and crisp "squeak" sound on the plastic floor or floor. Under normal circumstances, fake shoes will never have such a sound.
5. The function of sole: What I want to talk about here is the problem of carbon fiber sheet and TPU support sheet. When buying some new Nike products, most shoe friends will look at the carbon fiber sheets of shoes to judge whether the shoes are true or false. This method can see the authenticity of shoes at a glance, because the cost of carbon fiber sheets is really high, so fake shoes will not use carbon fiber sheets, but only find some materials similar to carbon fiber sheets to use, which will of course clarify the authenticity. However, although the cost of TPU stays is not low, there are imitation shoes on basic big-name sports shoes now, and of course they will be copied according to orders. In fact, this is also a trick to distinguish TPU. First look at its color. The TPU color of fake shoes is opaque than that of real shoes, and the texture is softer than real shoes.
There are also differences between real shoes and fake shoes in the shape of shoes and the direction of some lines.
Because the designers and developers who make real shoes and expensive shoes are different, the last and version of shoes are definitely different from real shoes, so the shoes with real shoes are definitely different from fake shoes, and there are many differences between real shoes and fake shoes because the designers have different versions of shoes on some lines.
There are many differences between true and false in some details of making shoes.
1. You can take a closer look at the midsole of the shoes. There must be some bumps on the midsole. Although the dots are small, you will find out what these dots are for when you walk around the midsole. Why are there these points? Because the midsole is to be burned in the mold, EVA is liquid before burning, so these liquid EVA must be introduced into the mold before it can be used in the mold. The method of introducing these liquid EVA into the mold is to introduce the liquid into the mold through a very thin introduction tube. The thinner the lead-in tube, the smaller the bulge left by the midsole, so developers definitely hope that the smaller the dot, the better, without affecting the beauty of the midsole, but this does not mean that it can be small. It requires a lot of factories. Generally, factories that make fake shoes can't reach this level, so the bumps on the PHYLON midsole of fake shoes are definitely smaller than those of real shoes.
2. Upper sewing thread: NIKE and other big brands have strict requirements on the sewing thread of shoes. It is stipulated that the length of each needle should be uniform, and there should be no jumpers. The workmanship requirements of fake shoes can't reach such a strict level.
3. In the process of shoe molding, the shoe with the bottom attached is placed on the last tree, so the bottom attached is also the last process in shoe molding. Because the factory level of big brands sticking to the bottom is very high, most of the shoes sticking to the bottom are neat, and the glue will not climb to the upper, which makes people feel very comfortable. If the sole is uneven or the glue climbs to the upper, the big brands generally don't. Those who pass the inspection will generally be sold to their employees as B products, while fake shoes will be sold out because they are not their own brands.
4. There is also the color of shoes. The color of fake shoes is often incorrect, because the developers of fake shoes have to go to different places to find materials suitable for shoes to be copied, and then dye them, which will definitely cause some color differences with real shoes, so looking at the color is also a good way to distinguish between true and false, and then remind those friends who love online shopping shoes that some super-abnormal shoes that are copied are ugly only by a few pictures, and you need to look at the real things and analyze them slowly.
The above is a better way to tell whether shoes are true or false, and I hope it can help some friends not to be deceived again.
P.S. specially presented the "James 2" of today's popular shoes: (circled in green, really in red)
Compared with the genuine product, the fake vamp is bright white, clear, bulky and hazy.
