Tip 3: All genuine Adidas products have serial numbers on the tags affixed to them. The tags have the size and product information on the inside of the shoe (behind the tongue).

Like their rivals Nike, adidas do a good job of providing an easily accessible code across all their shirts. The code (also known as an International Article Number), found on a small tag usually on the inside of the collar, is 6 digits long consisting of 2 letters and 4 numbers.

Look for the tag on the product which will have the size and other product information mainly inside the shoe that is behind the tongue of the shoe. Real Adidas shoes have tags with serial numbers for the left and right shoe. However, a fake product will have the same serial number on both shoes.

adidas is a multinational corporation, founded and headquartered in Herzogenaurach, Germany, which designs and manufactures footwear, apparel, and accessories. The sporting goods company also owns a share of the German football club Bayern Munich.
