No, almost near retail for them... Pretty sure if you look around, can find them for even less; I paid $130 for my Anthracites, and there not even worth that. Very uncomfortable shoe!
Those are definitely official. Everything looks good about them. You could also look at the sellers feedback and tell if they sell fakes or not. Dude has 38,000 + feedback, with 99.4% being positive. You're good. I do agree TBhova about these being extremely uncomfortable though.
These are still in my mall sitting, price reduced to $100 because the shoe is so poorly uncomfortable.You can bid on ebay instead of doing "buy now" auctions or do a massive search on google for legit sites. Or try the "other site" marketplace! Can't really tell you directly where you can find these as they aren't a highly sought after sneaker.
check your local CL and ebay do have them for the low... I got both binary's for 100 and 120 for the arthacite, i love mine dont have a comfortablity problem like everyone else i hear
