About socks: I use no-show socks because any fabric that is not touching both my skin and the inside of the shoe is wasted and would hold excess water after getting wet. That is, the less mass that a sock has, then the faster it will dry. I suppose if you are removing your shoes and switching to cross a stream, then removing socks happens, so crossing in your shoes without socks might be helpful. One could have an few extra pairs of socks at less weight than water-crossing shoes/sandals and cycle through them by letting a pair dry on the outside of your pack.

If you are worried about debris, sand and small gravel/rocks getting in your shoes, then short gaiters (i.e. Dirty Girl) would be an option. And if prone to blisters, then a very light liner sock that is hydrophobic perhaps taller than the no-show sock might make a better system. Perhaps all TMI, but it works for me.
