Hi Blink,
I found your dream really interesting, but don't feel comfortable with trying to interpret it as a whole... But do want to comment on this, "They were blue-green in color I think, and of some importance to me but I don't know why."
Blue-green is par excellence the color of healing, as it represents the balance between mind/Soul and body.
Its a very harmonizing, and soothing vibration, and often shows up strongly in the mental aura's of those who are natural and innate healers, especially those who heal both from a physical (with diet, exercise, etc. knowledge) and non-physical way (energy work, balancing others energies, knowing how the mind affects body, etc)....
So combine that with the symbolism of what shoes mean to you....
Good luck on the dream interpretation.
