I really like these jeans, just sad to see they have been discontinued by Levis.  Wearing a belt is a good idea, I do tend to have to pull them up quite often, but I know the size 11 would be too small for me, I got the size 13.  I am 5 7' and weigh 165.  I also got the tall size.  I hate high waters, haha.  They are kind of long, but with boots they work just fine.  I will be trying to find more of these in my size before they disappear.
