Mainly depends on your observation. Let's just say, look at his workmanship. If you don't know much about shoes, I'll be specific. First, the body of the shoe, observe all its trademarks. What's the difference? Will there be too much difference between different materials in the same color? If there is, it is imitation. Because genuine factories are not allowed to have chromatic aberration. Second, the face lining: see if the texture of the face lining inside is too hard. Not soft. Too hard is usually imitation. Then pick up the face liner and see if it is the last fit. That is to see whether the cloth inside the sole conforms to the material of the shoe body. More than 90% genuine shoes are made of last. If the sole layer is hard paper shell, or even cloth, it is really a low-grade imitation. Don't even look. Third, the sole. See if there is a trademark on the sole. If there is no trademark on the sole, 70% of the goods are fakes. Each genuine shoe has a special one. Shoe body. Fourth, look at the overall taste. Squeeze the whole shoe body by hand. If it recovers quickly, it's true. If you can't recover in half a day, you still have to recover by hand. 40% is fake. Fourth, pick up the toe and fold it down. There is not a trace of truth. High imitation with serious traces is more likely.
