I'll add another positive review of injinji socks: quick drying, quite comfortable after you get used to them, and durability seems pretty good so far. I sometimes get blisters between my toes, and managed to avoid this problem entirely during a recent trip to Utah between the injinji socks and a pair of golite sun dragons with a very generous toe box (if your shoes are already on the tight side, these might not work too well due to the extra fabric between each toe).
I did not use them continuously, but rather switched them out with some thicker darn tough merino socks. I really liked the option of giving my feet two very different "looks" switching back and forth through the day. One piece of advice is to try these out on a long run or day hike before committing to them on an extended trip- I can see some people just not getting used to them.
