I currently use Smartwool lightweight cushion Adrenaline (no longer made?) or PhD socks. But I've been thinking about switching to something a bit faster drying.
The current system: Wear one pair of wool socks. Keep other in pack. When feet get wet (e.g., stream crossing), switch socks. Hang other pair on back of pack to dry.
The downside to this system is that (i) if your shoes are wet you are introducing a dry sock into a wet shoe. (ii) it's not good to wear wet socks to bed. (iii) wool takes a while to dry (although it does insulate while wet).
Should I have a dedicated pair for sleeping? Should I bring plastic bags to go over my socks if I need to walk around in wet shoes?
I should mention temps are typical summer mountain temps, say, between 30-80 F.
