Two questions after reading this thread:
Why not wool socks if your feet are bound to get wet? Wouldn't the wool keep them warm enough?
ANd yes, we wear a liner sock to get moisture away from the foot when sweating, poly pro of some type usually, followed by a wool sock.
I stepped off into a bog in Colorado once... it did not look like it could be much of anything, but with full pack on I"m glad it dropped off right away and that I grabbed a spruce sapling... my left foot never touched any bottom, and was up to my waist when I caught myself.
Water was cold in late September at 10K feet.
Wife and I were hiking out, and we went far enough that the pants and socks were basically dry by that evening. Cotton would not have been so friendly.
