+1 to this.
That's not to say someone's feet aren't getting cold. I remember having the same questions about cold feet and it's maddening when nothing seems to work. Stuffing thicker things into my shoes never helped, because cutting down blood circulation just makes it worse. Same shoes same socks and I'm fine at 30°. One thing I did discover: keep the lower legs warm and the feet will stay warmer.
