Try and knock the snow/ice buildup off the laces/top part of your boot as the day progresses - don't let it buildup and consolidate. Vestibule of the tent is your friend at the end of the day (if you have one). Again, bang out your boots as best you can, brush the laces out and try to clean off the ice as much as possible. I've yet to stick my full boots in my sleeping bag. If conditions are that cold, in my opinion, you should be in double boots anyway. Bring the boots in your tent for sure, if you place them between your body and your tent mates, they'll stay warmer. Good spot for water as well if you aren't insulating it otherwise. They aren't going to be toasty when you put them on in the morning, but you're in the mountains in the winter...also, put your fresh socks against your skin for a bit so they can get nice and warm before you put them on.
Solid advice. If you're in a good 4-season tent, the interior should be warmer than freezing (unless it's just terribly cold and windy). Placing the boots inbetween the sleepers will help keep them warm and dry them out some as the dry mountain air and ventilation should reduce some of the moisture. If they have removable footbeds, take those out and place them in your sleeping bag, and make sure the boots are as wide open as you can make them (loosen the laces and pull the tongue away from the back of the boot). Opening the boot all the way up will make sure that even if they DO freeze, you can get them back on.
Socks - I use three pairs of socks. One pair for hiking only. One pair for in camp only. One pair in the sleeping bag only (also known as the 'sacred sock.')
Hike all day in your hiking socks. When you arrive at camp, put on your camp socks and your bootie system (or camp shoes like crocs, etc). Place your hiking socks inside your jacket near your skin or in contact with your skin. I usually put them over my shoulders under my softshell jacket. The idea being to use your body heat to dry them out. This takes time, so you need to get on it immediately when you stop hiking.
The sacred sock goes on ONLY when you are in your sleeping bag. You need to sleep in dry socks to help keep your feet in good shape. The hiking socks and the camp socks go in the sleeping bag with you, ideally in direct contact with your skin.
If the camp socks are not dried out in the morning, hike during the day with them tucked inside your jacket somewhere they won't fall out, and the movement and heat will dry them out.
I spent 20 days on Denali with this system (and Spantik boots) and had no cold-weather problems or blisters.
I spent 3 months in a NOLS outdoor semester in terrible fall snow conditions (with single leather boots that kept freezing every night) and all the way through to winter in Wyoming with this system.
It will save your feet.
