Cozy trainers? Or alternatives?

[FromageFred]

I am firmly a trainers person for every day wear, with the occasional foray into flat boots. However, it's getting cold, I'm getting old, and I need something warmer this year.
I can't see myself wearing Uggs, and I tried on some furry DM biker boots last year (these: www.drmartens.com/uk/p/womens-boots-oily-illusion-hi-suede-wp-gayle-fl) which just didn't suit me somehow.
What other options are there? Do warm trainers exist?

I had some faux sheepskin lined supergas once. I've also seen sheepskin lined converse, and Ugg trainers.

Alternatively get some sheepskin insoles from Amazon for your current trainers.

I think you might be in luck this year cause I've seen fur lined trainers and high tops in quite a few places. I'm currently helping my Mum use her M&S 20% code and wondering if I need to try their sand coloured version!
