If impurity affects the bottom of a woman’s long garment, does her walking in pure places purify it?

Question:
He says: Honorable Shaykh, may Allah grant you success. Some jurists mention that if a woman’s long garment walks on impure ground, her walking on the pure ground that follows purifies it. Likewise, they mentioned the sandal; they considered it like the sandal, where if there is a trace of impurity on its bottom and it is rubbed, it becomes pure, just like the woman’s garment. This is part of removing hardship from this Ummah.

Answer:
Yes.
