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.

Checking the serial number is one of the easiest ways to verify the authenticity of Adidas shoes. Fraudsters producing fakes often overlook this very detail. If you have an original pair, you will find the unique identification code on the inside of the shoe.

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).
