I put Arctic Shield over my 1000gr Thinsulate boots last week and they helped a bit. My feet were frozen. Then they weren't as bad. They weren't easy to get on, even sitting on the ground. I probably wouldn't have been able to get them on in a portable. It was cold -20F to -10F. I was really wearing the wrong boots anyway, too light, and was kind of banking on the Arctic Shields. If I'm packing my cold weather suit into a spot, I might as well pack in some more insulating boot covers/blankets, or pack in heavy boots. I am going to check out the IceBreakers too.
Are you saying they didn't help or they did? I'm confused because you said your feet were frozen then weren't as bad. Have you tried them with light boots without as much insulation? I noticed with rubber boots (especially insulated) my feet froze. Rubber holds in moisture and keeps the heat from reflecting back like they are supposed to. Also, if you get snow or ice on your boots, that will make them act as a cooler. Now, down here in AL we don't get those kind of temps you mentioned but it's still cold because it's not a dry cold. I use 400 gram thinsulate boots and they work for me. If it gets down in the low teens or very rarely single digits, I'll have to drop in a hand warmer. I'd rather carry those than something bulky though. Mine fit pretty good, but if I was going to put them on big boots i'd get the biggest size. I've heard of people taking off their boots and using just the covers....I tried it on my porch for a little bit and it worked. I think each person is different based on their circulation etc. too.
