Thanks for the replies. I know about liner socks, outer socks, and enough room for you toes to move around. My feet are getting so big and flat in my old age (they're 12 EEEE in shoes) that finding boots big enough for my feet and two layers of socks can be a problem. I currently have a pair of Cabela's boots with 400 grams of Thinsulate. I haven't had them on since last winter, but as I remember I can't get two pairs of socks on with these boots, and they are size 13.
I bought a pair of Arctic Shield boot covers last year but they were too small. I forget what size they were, but they wouldn't fit over my hunting boots. I think I waited too long to buy them and they were only size XL, and I need XXL.
I'm still looking for recommendations of electric foot warmers if anyone has them.
