First of all, don't be greedy for petty gains, because the real Adidas is uniformly priced, and even if there is a price difference, it will never be great. If it is half or more cheaper than a specialty store, it goes without saying that it is very likely to be a fake. The second letter D of the real Adidas is connected with the shortest bar, and the third letter I and the fourth letter D are connected with the middle bar. The three diagonal lines on the trademark are connected with the upper corners of the two D's, and the genuine embroidery is more delicate, with no thread ends and proportional spacing. Mainly depends on the gloss, the real reflectivity is very good, and the false reflectivity is generally poor. Also, look at its stitches. If there is a double needle, it is fake. There are also three lines on the clothes that also have trademark significance: these three lines are fine in workmanship and symmetrical in size. Moreover, the distance between the three lines is consistent with the size of the lines themselves. The number of stitches for an inch of suture is about 10. This is the basis of overseas investigation. Counterfeiting manufacturers will never follow this strict specification! One more thing depends on the listing. Adidas has strict requirements on color and paper. Usually 2-4 pieces of clothes are strung together to see what style they are. You need at least two. One is the main label, usually black. There are few blue main tags in China (unless they are old models a few years ago), and there are also certificates. There's a money number on it or something. Very detailed. And if it is a special fabric, there will be a separate label to explain it. Moreover, it will be printed with strict and uniform color numbers and fonts, and the paper is also very good, without wrinkles and very soft. Merchants will give you a price different from that of general Adidas, which is the charm of the brand.
