I have the same problem and I agree with Phat....get them tailored to fit properly. I used to just roll up my pant legs because a 30" inseam is just to long, but I can't find pants with a waist that fits me and a matching inseam. Nothing wrong with having pants modified...I just purchased a pair of convertible pants and had them hemmed up a bit to make the fit better.
