There's a lot of complaints on here because Levi's apparantly changed the sizing versus the old 505's.  I never owned a pair of those and probably would not have owned a pair based on the other gentlemen's opinions.  I prefer a lower rise because I do not wear my jeans up to my belly button.  I also monitor eat healthy and exercise regularly, so a slightly trimmer fit is more appealing. It also sounds like a lot of these gentleman complaining have a relatively large midsection compared to their height, so perhaps that is the problem.  My opinion of the 505's is that they are a nice straight fit, not too tight like slim and not baggy like relaxed, with a moderate opening at the bottom, not as big as bootcut but not tapered too tight.  These are my first Levis since middle school and I am impressed.  Modern fit while still comfortable.  Thumbs up.
