I have handled fake sneakers in the past, and I have noticed two things that easily identify the ones I've handled. Firstly, the construction was shoddy beyond all acceptability. They felt like they were going to fall apart the first time I wore them, and the materials used to construct them felt very cheap. Secondy, brand new, they had a very unpleasant "synthetic" odor to them, different from the typical smell of new sneakers. That's not to say that fakes can't be produced well and without an odor, but if your sneakers have this, then they're probably fake.
Also, one way to spot fake Prada is by examining the logo on the box. On the genuine box, there is a small indentation between the loop and the legs of the R in "PRADA." On a lot of fakes, this detail is neglected. Like so:
The image on the right is of a real box, and the image on the left is of a fake box. If your box doesn't have this detail in the R, then your shoes are fake.
I also stand by my original statement that even if they are real, they're not worth wearing considering the fact that they're hideous. Fake or real, those shoes are a disgrace to humanity and should be burned immediately.Edited by nerdoldnerdith - 8/19/13 at 7:38pm
