Upper technology, such as hot cutting, micro-injection, etc. It must be made of TPU, and most fake shoes are made of PVC. They are the same in appearance, but TPU material has high cost and good flexibility, while PVC is not. This material has no elasticity, poor flexibility and is easy to break in winter. Shoes with real soles will be mixed with some chemical raw materials to make them more wear-resistant. Anti-skid performance is more prominent. The outsole of fake shoes is far less skid-proof and wear-resistant than real shoes. When you wear real shoes and rub the ground with your front foot on the plastic floor or floor, there will be a very loud and crisp "squeak" sound, which is absolutely not the case with fake shoes. In addition, you should pay attention to some stitched or embroidered parts of the upper. Fake shoes are generally not done well in this respect, and there are often exposed lines. Also, pay attention to the shoe box. It's best to check the product number online and compare it with the one printed on the shoe box to see if there is any difference. Then, pay attention to the shoe label on the tongue. Fakes are generally poorly printed. Origin is also very important. Nowadays, Nike's basketball shoes are almost all made in China. Running shoes and sneakers are also found in Southeast Asia such as Thailand, Indonesia and Vietnam, while Adi is almost all made in China. If you find anything made in Korea or Taiwan Province Province, you should be careful. These big brands have moved their large-scale production lines to several OEM factories in Guangdong and Fujian in the middle and late 1990s. The original mass production bases in Taiwan Province Province and South Korea only do a small part now, and most of them are commemorative funds. Now fake shoes are getting better and better, and some of them are difficult to distinguish from the appearance, so the safest way is to go to a reputable store.
