My feet stayed toasty warm in Thinsulite insulated boots. I like those better than the heavy Sorel packs. I wasn't standing around though, my job was walking a lot, and if I move, I keep warm. You can't take the liners out and switch them, like Sorels, but I have a boot dryer.
I think the air filled boots are called bunny boots. They didn't used to make them in my size or I would have tried a pair when I was a lifty at the ski area. Some of the guys had them.
It stayed at 52 in the shade today. The strange bright orb made an appearance this afternoon and it even smelled like spring. I have crocus flowers that will be blooming in a day or two. I transplanted some primroses, which are colorful and were on sale and still might freeze if winter returns. The rose bushes are leafing out. Strange weather and I guess we should be hollering about global warming. Don't move here.
