Alright, what you do is you put your fuzzy (Wigwam is a good brand, as is LL Bean) socks into the dryer for a half hour. When it buzzes, you take 'em out and you cram 'em into a thermos. You put your thermos in your truck. You go do shit. When you're done doing shit, you take your socks out of the thermos and put them on your feet - and then you put on fuzzy slippers.
You drive home with nice, warm feet!
Be sure to put some hot water in there too, keep them extra toasty warm.
