well i think that most of the clothes sold on e-bay are fake...
no way that those prices are of the real deal....
i have bought 2 pairs of Puma sneakers limited edition...of Mihara Yasuhiro...payed 250€ per pair...but they are so real, at the time when i was buying them i have never asked myself about the authenticity of the sneakers...i am wearing now them for more then 1 yr. and a half and they are of excellent quality...so i suppose even if they were fake they are of excellent quality and good looking...
maybe i've bought real ones...one thing is sure...i like them as they were real!
I have the red ones and the black one with Puma Disc system...
