It sounds to me like she has a bit of a respect issue. I would do some ground work with her to reinforce her respect for you. If you show halter, practice your showmanship skills, walk her around obstacles or in patterns making sure that when you turn, she turns appropriately without letting any part of her body touch yours and keeping your personal space. She must stay with you, but not touch you. If you make a sharp turn to the left and she doesn't follow and leaves her butt behind, give her a light tap with the end of the lead or a crop to let her know she must move her rear. Backing, backing in circles, etc.
I know none of the above sounds like it will help you pick her hooves, but it will impress upon her that YOU are the lead horse, YOU make the rules and you command respect. The respect will help you with the hoof situation. Once you get the respect in order, work more on picking up feet. Do it any time you think of it, not just for picking hooves. Teach her that she is to release her foot to you ANY time you want it.
