'The two things I noticed when I started barefooting (essentially the same thing as wearing Vibram FFs) was how much better my balance was and that my middle aged "bony" feet started getting fleshy again. My foot is wider but shorter as my arch has lifted quite a bit.
And I can't stand any shoes with heels. I wear my Mountain Masochist trail shoes and I feel like I'm in high heels.
you may have convinced my flat footed self to give them a try
