You wont be able to buy them from Diesel Online Store USA.
Only people who live in USA can buy from there same as Germans can only buy from Diesel Online Store Germany.
To your questions yes of course it is genuine ;)
You have to see them in real :S
I like the wash but the pair I saw had several dirty (brown and orange) parts on them which fucked the Jeans up.
The denim is a bit like 74k.
Maybe you will change you opinion when you see them in real ;)
No I'm not working in a Diesel Store.
