This, pull those insoles and wipe em off the best you can, then sleep with em. The rest of the boot is gonna suck for a bit, but once you get moving it all works out. Also, I just screwed up this last trip and didn't loosen my boot laces up when i went to bed. Next morning I stuffed insoles back in but broke a lace trying to loosen my frozen boots up so I could slip my foot back in!You can also remove the insoles of the boots and bring them in your sleeping bag to help dry them. If you use a down bag, be aware of how much moisture you are putting in the bag if you have a longer trip without ability to dry it out in the sun (use synthetic bags for this). If you are doing trip in winter/below freezing the whole time conditions that is multiple days, double boots become critical. Also consider leather vs synthetic, as many leather boots will not dry as easily.
