Fraudulent, imitation, bogus, counterfeit, knock-off, fake... whatever word you choose to describe non-licensed brand names products, they still remain somewhat of a novelty.
The quality of these products, usually made in south-east Asia, can vary greatly, from becoming defective in one day, to "I can't believe it isn't authentic!".
The fake Nike brand shoes as pictured here though, are pretty laughable. As you can see, the fake brand imprint transforms itself to a temporary-tattoo.
I've heard worse though. On a TV show, there was an imitation diamond ring that dissolved in water.
