Are the shoes on the Internet Type B??
Most of the shoes on Taobao are imitation shoes, because the price is set there, that is, 30% to 40% off of the original, which can't be true. And imitations can be good or bad. I suggest you don't go there. If you buy defective products, it will be troublesome. Returning them is very annoying. The so-called model B is genuine, but it is found to be defective when it leaves the factory, which does not meet the factory standard.
