A suitably high, technical sock with a good fit and high durability.
25% of the sock is wool, which keeps you warm even if the sock is damp. Comfortable to the skin
It is important to sleep with dry clothes on the body at night.
This also applies to the feet. So bring a pair of socks for your trip. One is used during transfer, and can be hung to dry on the tent rope or in a tree at night. The other is used in the camp - if you have dry camp shoes with you - and in the sleeping bag.
