How to always have dry socks with only two pairs

On longer snow climbs such as Mt. Shasta and Mt. Rainier,  (not to mention expeditions) keeping your feet in good shape can be a challenge.  Even with plastic boots, your socks and feet will get progressively more wet if you do not take proactive steps to dry them.  Here’s a tip to have dry socks every day on long snow climbs, while bringing only two pairs. 

1) Wear a pair of socks (pair 1), get them wet.
2) Hang pair 1 up in tent that night and all next day.
3) In morning, put on fresh pair (pair 2).
4) That night, hang pair 2, and put pair 1 in the sleeping bag with you, and put a hot water bottle inside each sock (preferred), or put the socks on your belly.
5) Repeat indefinitely.

(A guy who walked solo to the North Pole used just a single pair of these RBH socks for over 72 days – with no liners, no vapour barriers or outer socks.  Impressive!)
