I went winter camping this weekend and my feet froze today. I have lacrosse's and bunny boots. I used the bunny boots today and my feet froze. I also had a pair of wool socks on. I have cold feet and need a good pair of boots. I'm just wondering what you guys recommend. My bunny boots keep me warm if I prewarm them i.e put them on the boot drier for a hour or so before I got out. I don't can't do that from the tent. Any ideas would be great.
