1. Bar code on shoes. Generally, those brands of shoes have bar codes on the upper surface of the shoes, which are usually hidden under the "tongue" of the shoes. You can know the authenticity of these shoes by scanning the code yourself.

2. Pay attention to the words and icons of the brand. This is a common problem of counterfeit brand-name shoes. There will be some changes in the words or icons on brand-name shoes, such as missing a stroke or adding a punctuation mark that we almost ignore, so we must pay attention to this when buying shoes.

3. Pay attention to the workmanship of shoes. For example, if you write a needle and thread and there is glue, it is impossible for a really good shoe to jump with a needle and thread. There is some glue on the outside of the shoe. Only fake and shoddy shoes will have these situations.

4. Try to buy it at the counter. Generally, counters in physical stores are almost afraid to sell fake shoes, especially in big places. Once the fake and inferior shoes are sold, they can't afford the consequences caused by customer complaints. Therefore, if you want to avoid buying fake shoes, you'd better go to the counter to buy them.
