Thanks man. I'm 5'11" and would definitely hem these. I already have a pair one size smaller than the pair pictured but the rise is just not high enough to wear comfortably on a daily basis. That said, the smaller size I own fits perfectly everywhere else. With this pair I'm trying to get a little more breathing room without them looking sloppy.
I had the same problem when I first bought mine.. I originally bought a 31, went back and got a 30. The 30 was uncomfortable at first, but with wear it stretches very fast.. especially in the waist and thighs.. it will eventually get looser and easier to wear.
