Putting your feet into wet and frozen boots in the morning is quite possibly the most challenging aspect of camping in the snow. Cold feet before you even leave camp is a guaranteed for frigid toes midday. Those wet socks and liners won’t get any drier as the day continues.
When you get back to camp each afternoon switch over into a pair of lightweight down slippers (although avoid close contact with your feet and snowy surfaces) and take your ski boots off. Take the liners out of the shell and put them inside your tent or hang them to dry somewhere if possible. At night, when you crawl into your sleeping bag, put your liners at the bottom of your bag. If there is no room or you can’t sleep with stinky liners, put them inside in the morning when you wake-up for a bit of warming before stuffing them back in your shells.
