So, my mother praises her 530s for being the most comfortable shoes she's ever worn and refuses to buy anything else as a lifestyle shoe. I wanna gift her a pair of either 993s or 990v6s, hoping to show her what a real comfort is. She wears a W 7US/M 5US in the 530s. Should i stick with the same size for the 99x or should i size up by a half? Thank you.
