umm, no. at least not all of them. I've owned 5 or 6 different pairs in different cuts and all have been huge- need to size down in every case 1-2 sizes from my normal Diesel size. Actually, the only pair of DDGs that's fit me well was a slammer/darron pair I have in a 29, and I typically wear a 30w in both those pairs (with the exception of 8WW and 61X-need 29w).
I owned a 33 in the first DDG raw and when I compared the measurements on the orange above to the ones I had, they ran even bigger; maybe the guy just doesn't know how to use a tape measure or they're really stretched though. Cez, didnt you feel those raws ran big on you? Personally, I'd prolly need a 30w in either DDG raw and I usually wear a 31w in regular Thanaz.
