I am not quite there yet regarding posting myself on social media sites, sorry to say.
I don't know why these need to be limited to warm weather only. I have been known to wear ivory tights underneath, they are too good for my intended uses to give up on them for six months or more of the year.
And I rarely wear anything but flat or low heeled footwear, including with these. Mainly because I find heels to be less than comfortable and hard to walk confidently in, secondly because I am 5' 9" (thanks, dad) and feel like that is plenty tall enough.
Did Hepburn wear heels with her trousers? I'm picturing her in oxfords, but where that picture is coming from, I don't know! I'm sure that's wrong, at least in movies she must have worn heels, such were the times.
Try a search on your preferred retailers' websites for 'wide leg' in pants, you'll likely find the same style and color pants somewhere at a more reduced price, making the CPW work better for you. You DID say you have unreasonable love for them, I'd say that makes it worth finding a way to make these pants work for you!
