The internet is probably fake. A few days ago, I read a report that there are many fake workshops in Guangdong, large and small, which are busy at night, specializing in the production of this brand-name sports shoes and the like. There is only one official authorization online. I often buy famous brands online, although I know they are fakes, but the quality is much better than that of miscellaneous brands, and I don't go out of shape. In fact, you don't have to care too much about the brand, as long as the quality is good.
