Injinji toe socks come in several weights (light, original, medium), ankle lengths (no-show, mini-crew) and colors (white, coal, black). I know many like the black, no show, lightweight but the no show is just not high enough to clear some shoes and the lightweight doesn't protect enough for me. My combination of choice is black/coal medium weight mini-crew.
[Note - I haven't done any river or stream crossings so I can't comment if light or medium weight would make a difference in how long it would take socks to clear water and dry out.]
You must give Injinji medium weight, mini-crew toe socks a try if you are at all susceptible to toe blisters.
