Its great that you are experimenting. Be prepared for people staring at your foot-like shoes. You may want to try keeping your vibram five finger running on grass or at least dirt, and getting into it as gradually as possible, although if you already do frisbee barefoot you might be ready to go at it hard. Our feet did not evolve to constantly run on concrete, although they still absorb more shock than any running shoe. You may also want to try practicing raising your arches by gripping the floor in such a way that your toes bend backwards and you make contact with the big toe and little toe ball of the foot.
