Heh... it's just inertia with her... I have a feeling once we shoe her, it'll be forever. Not that there's anything wrong with that :~) That's normal, as far as I'm concerned.
Well, I think it's a healthy thing to let a horse go barefoot when you can. I only keep mine shod all the time because I ride all the time. If you know 100% for sure you're not going to ride thru the winter, I'd pull the shoes. If for no other reason then to save the cost:)
