It's not strictly necessary, but moderate compression (15-20 mmHg) provides a noticeable benefit on tours longer than 3-4 hours. It improves blood flow, reduces foot and leg fatigue, and keeps the sock from sliding around during the walking motion of skinning. If you've never worn compression socks, start with light compression and see if you like the feeling. Most touring skiers who try moderate compression don't go back to non-compression socks.
