It’s the full booties I have. They’re almost too insulated. I still get cold feet but slackening the shoes off helps. I’m even packing ‘foot warmer’ pads that people use for skiing, just in case it’s brutal. Never tested them but if it gets bad enough to try them then it won’t matter anyway.
I took (and used) chemical foot warmers last year. I think I might still have some. It was hard to say how effective they were - I hadn't felt anything in my toes for days.
