A pair of shoes have different shoe labels on the left and right feet, and the probability of fake shoes is still very small (manufacturers will not make such a low IQ to deceive customers). The main reason lies in the negligence of the clerk, either because he accidentally put on two different shoe labels, or because the customer accidentally put on the wrong money, which is irreparable, or irreparable. At this time, the clerk simply made a mistake and sent it to the new customer-you, this is not a fake shoe, just a beautiful scam, trying to get away with it.
