What do you wear on your feet with 7/8 trousers in the winter?

[SafariOrigami]

I saw some really lovely trousers this year, and I love 7/8 length in summer. But what do you wear in the winter?
On the websites / books they are styled with bare feet and flat shoes or heels but I cannot imagine bare ankles in the depths of winter!

So please tell me what you wear. I would rarely wear heels, so flat options would be best for me. Thanks!

I just saw a woman wearing them with ankle boots. Quite tightly fitted round the ankle with a medium height block heel. Trousers and boots were both black. She looked quite good, but I also think it would be very easy to get it just wrong too. She had an elegant camel coat which helped!

I wear high heeled ankle boots. They're higher than they look in this picture. Have I made a major fashion faux pas?

Pop socks, in nude or possibly opaques in a suitable colour (not black as a default) or long boots over the top.

I have worn by Chelsea boots with mine and they look good
