I bought a pair of Vivo Dharma last fall since I needed a "dressier" shoe than my VFF for job interviews and whatnot.
I love em! A little expensive, but for the money they've gone through snow, me being on my feet all day, etc.
Totally worth it.
As far as barefoot walking and running is concerned... And I know this is a CRAZY idea, but do it barefoot.
VFF are great, and for day to day stuff where you can't or don't want to be barefoot they are super.
But if you are training outdoors then I'd say leave them off and work your feet. Slowly and properly.
Barefoot lifestyle is slowly turning into a gizmo fetish. Trying to do things in 20 different ways that are "like" or "almost" barefoot... Try barefoot.
Once you learn that you create your own reality and that you are fully responsible for your life, you can begin to see the world as it is and then you realize the limitless possibilities.
