ebays so random, ive seen the de la souls for like 60 and the hawaiis for like 70, but overall you got good deals on both because a lot of the time they go for way above what you got them for.
if that pic of the de las is the shoes youre getting, it looks like you got had...the swoosh is so off, i dont even think they tried to make em look legit. and the midsole is way too thick too. hopefully you didnt end up with fakes.
That last pair your posted are most definately fake. I'm not sure if yours are or not, but if your buying stuff on ebay, I'd try to find a good sellers list or something.
go to nikeskateboarding.org, they have a whole forum for just how-to's on spotting fakes. also, if you can get onto niketalk.com, they have a legit check forum too, so you can just post pics and the heads over there will let you know.
you can find deals on ebay u just gotta know how to spot fakes and get good pics and shit. nsb.org is great and there are guys on there that will help u out if u post pics from the auction. i have both those pairs actually. mine are real. and i am not sure about urs. de las are more suspect than hawaiis. get a pic of the insole where the chick is and i can tell u for sure if they are real or not. and if u can get a pic of the tag of the de las i could do the same for those. it really hard to tell without pics of tags. thats the most definitive way to tell.
