Might just be where I live (Edinburgh) but I am seeing skinnies out in the wild more, now that we've hit slightly cooler temps. And I mean skinnies as part of a styled, intentional outfit, not "I never got round to buying new jeans." (I am in the camp of "never threw mine away", but I also wear lots of other styles, including some quite exaggerated horseshoe ones and some vintage straight leg Gap and Levi's pairs).
What to wear with wide legs - I like them with slim loafers, pointed flats, or heeled boots, but sometimes wear mine with platform trainers for a more casual look.
As for what's in fashion - I still mostly see wide leg jeans out and about, but I suspect they're past the point of "cool" (if you care about that!) and into "accepted default". Barrel/horseshoe styles a close second but they're more divisive. I'm not sure what's coming next; there are lots of articles insisting skinnies are making a comeback, and certainly slim cut jeans have been sent down plenty of catwalks, so maybe the proportions are about to swing again. And straight legs were never "in" enough to truly be "out", or vice versa, IMO.
Right now I feel like we're in the "anything goes" space, which as a denim fiend is great - I think it's more about pulling together interesting looks and playing with all the elements of your outfit, rather than worrying about which style of jeans are fashionable.
