Amen to wringing them out. I regularly get wet feet. The trick:

1) wear socks that can be wrung out - I use a good poly liner sock and merino wool hiker.
Both when wrung out feel almost dry.

2) if they feel squishy, stop in short order and do the above.

3) They have to fit well, or you'll blister anyway.

Of course, the usual blisterism's apply - carry blister covers and cover them as soon as
you start to feel a hotspot, or it just gets worse.
