She is very cute. I don't know about conformation, trying to learn but not there yet. People say that about white feet, my sister has a paint with white feet and our farrier says he has some of the best feet he has ever seen. I would ask about the founder, either of the person or preferably when the vet or farrier checks her. I'm not a fan of shoes myself, expensive and don't want to be stepped or kicked accidently by a horse with shoes on.
I tell all my friends when they go looking for a horse, if its for trailriding buy a trailhorse, if its going to be a horse rode in a arena and stalled buy one from someone who stalls and arena rides, especially your first horse, you just spent a nice chip of money do you really want to spend more on working with issues such as stalling, spooky because they aren't used to that kind of thing.
Good luck, I agree she looks like she has some arabian in her too. She sure is purdy.
