I've seen this one in a physical store. True or false, first of all, from the price, if it is too different from the store, it may be a fake. The second is comfort. Can I try it on in a physical store to see if it feels the same as what I bought? The third is the shoe size, some fake shoes, the same shoe size will be bigger or smaller than the real one. It is not easy to tell the truth from the package.
