Mitzi Perforated Venetian Loafer (Women)

I still love so many of my Johnston & Murphy shoes, but something has changed in the sizing of the shoes. This is the second pair, but a different style, that I have had to return this month because of the fit. My normal size is too tight because of the pointed toe of the shoe (which shortens the toe box), but a half size larger is too big. In both sizes and in another style shoe that I ordered, the heel moves up and down when I walk. It is disappointing since I love the look of the shoe.
