Had fun reading through the last 8 years (well, really just about 20 pages, but 8 years sounds cooler) of this thread last night. Finding a pair of 5010XX 6X6 for sale on clearance last year literally got me back into denim full-swing. Thank you Skull, thank you Analchemist, thank you Ppoduced by Fabfour.
I only wore them for a few months, though, because I started going denim crazy again, buying new pairs. They've been hanging out ever since.
Tried them on last night and just love the fit... above the knee. These are indeed "slim straight." My first pair back in 2007 or 2008 was 2 sizes smaller, so there wasn't any bagginess going on down the calf/leg opening (but alas, I am now in my 30's and have no business sizing down anymore.)
Debating just storing them for good as a keepsake of my first Japanese denim, or coughing up some good cash to have them hemmed and tapered from the inseam...
