Obviously everyone's feet are different so all I can do is tell you what worked great for me so you have that option on your radar.
I love hiking in my Vibram FiveFingers. I wrote about it a bit here:

I like the freedom it gives my feet to move. The lack of ankle support can be scary to some people. To me it was OK because I'm lightfooted enough to respond quickly in case I make a wrong step or anything. I think that is key to success with FiveFingers. I got the idea that most people here would not wear them because of the lack of ankle support, and honestly I would be cautious about that too in case you're going out for days alone to a remote place or anything. However, I prefer to flex with my feet joints against any contours in the terrain rather than be strongarmed (stronglegged?

) into some stiff posture. The latter ends up hurting me more than actually supporting me because, well, how much can the little ankle cuff on a shoe really support a 200-pound guy
Anyway, they dry quickly, offer lots of mobility, are very light, and are very fast.
FYI: I have flat feet;
every other shoe I have ever worn hurt my feet a lot starting at about 22 years old (I'm 26 now) except these Vibrams; my pinky toes are not straight and curl under the next toe a bit; I walk on the balls of my feet rather than using the whole sole (most people land on their heels and rock forward, propelling off the balls of their feet). I flex my feet a lot when I walk. I don't like keeping them stiff.
Thick hiking socks and any type of cushioning, including "flat feet correctors," also seem to hurt my feet a lot, so obviously I'm a very bare-foot guy for reasons I wish I could diagnose.
