If you find them outdated you're either not wearing them right, not the right sort, or else they don't do anything for your individual busy shape in which case, sure, don't wear them.
This won't apply to everyone.
As I said on the coloured bootcut thread, they do suit my V-body shape, by balancing me out a bit more, especially since I'm tall. I have one pair of bootcuts which are, needless to say very long, and also incredibly flattering. Would be foolish not to wear them just because of someone else's perception of them.
Other than that, I wear straights and avoid skinnies as they do nothing for me.
There are plenty of places to get bootcuts, it's just a matter of sorting the wheat from the chaff.
