The name adidas came from the founder, Adolf “Adi” Dassler's name. He used his nickname, Adi, and the first three letters of his last name, Das, to create adidas.

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.

Adidas sizing is generally true to size. The label themselves advise that for a more loose feel, you should go up a size or, for a more snug fit, try a size smaller. These are, after all, relaxed sports-oriented pieces that need to fit your particular lifestyle.

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).
