How to stop others' imitation? If there is no brand and no competitiveness, it may depend on novelty. What should I do?

Apply for a patent on the appearance of shoes, what color to match, etc. If you can apply for a patent, you don't have to be afraid of counterfeiting. You can go to any market at any time. If there is something similar to your shoes, you can report it to the industrial and commercial administration department and check it out. You can also apply for compensation. That's the process, but it's difficult for you to apply for a patent. Good luck!
