Input:
I've been wearing Ingenious socks since 2001. Very comfortable, decent wicking capabilities, especially in Iraq and Texas.

You do need to be careful with the dryer though. The socks that I brought to Afghanistan this trip were rendered useless by the Fluor laundry guys and their super-hot jet-engine dryer. The microfiber liner melted into individual prickly little strands that feel like I'm wearing a sock made of concertina wire. I ended up switching to Wigwams' Merino/Silk hiking socks for the rest of this trip.
