I ordered both the Manti and the Sirona to see which one would work best. It was a tough decision as they both were great. I usually wear a 7.5 in shoes and these fit true to size. These are patent leather, which somehow escaped me when I ordered them, to formal for this girl. So I chose the Sirona. Highly recommend this shoe for woman who like the patent leather, they are very comfy, they do run a bit more narrow than the Sirona.
