Cold or damp boots in the morning - make sure they are dry and not cold
One related tie-in that a lot of ski racers use to keep their feet warm: anti-persirant spray, the old-school kind, works wonders on feet that are cold. It's essentially a way to inhibit moisture build-up in your boots. when combined with a thin, wicking sock, your feet will stay warmer for a longer period of time.
I always have a can of the old, trusty Right Guard in the boot bag, and it works wonders.
If you have a tough time drying out your boots overnight, try removing the liners from the shells, then placing the liners and shells in front of a basic fan. Also, you can get devices that will work on the liners without removing them from the shell, though it won't take care of all moisture build-up w/o the liner being removed from the shell.
Then there are those who just have poor circulation in their feet. For them, barring everything else, look into electronic boot heaters: Hotronic, ThermIC, etc.
