Hi Phyre
Shoes generally represent "steps" we are taking in life.
When I read your post, what comes to mind is that you have a lot of shoes LOL! Lots of choices - some work, some don't.
You know sometimes people say "walk a mile in my shoes." Are you fulfilling lots of roles?
Really, the more important question would be how did you feel in the dream looking at all those shoes? Overwhelmed? Was it humorous? Were you just neutral?
And as for the little girl shoes... it could represent something within you needing some guidance too.
Anyway... that's just a starting point Phyre, and strictly from my point of view... there is just so much that goes on within the dreams, our feelings and thoughts are just as important as the symbols themselves
