The new Injinji socks I mentioned (which are coming SOON - they claim Holidays 2010):

Trail toe sock (nuwool) in mini-crew: http://www.injinji.com/tetratsok/o_mini_trail.htm

Midweight performance toe sock: http://www.injinji.com/tetratsok/p_midweight.htm

I read about them on their Facebook page. Facebook, it turns out, is good for something.
