The cost of a real shoe logo is very high. Moreover, a standard only corresponds to one shoe, while fake shoe dealers want to make huge profits in the short term and can run goods, and some never think about selling real shoes at all. If you wait until the real shoes are on the market, and then do it on the real shoes, it will take too much time. This is not the purpose of their fraud. At present, making money is enough. They don't care about making the shoe logo real.
