I had originally wanted the same shoe without the bow (can't remember the name) but am happy I didn't find it! I usually wear a size 7 shoe but it depends on the style, so I tried the 7 and 7.5 Vinnie on in a shoe store that didn't carry the black color and found I needed the 7.5. The bow you make determines how tightly the ankle strap fits, which is great. They came quickly (thanks prime!), just in time for a wedding I was attending. They are very pretty, and I got complimented. I rarely wear heels these days so I took my foldable slippers (not bedroom; they look like flats) with me since I figured I'd need to take the heels off after a few hours. We ladies know how that can go - cute and stylish can equal torture later. I was so shocked at how comfortable the Vinnies were! I danced and walked and stood for about 7 hrs total and never once did I think about my slippers. I take that back - I thought about taking them back to the car but the pouch they were in coordinated with my outfit so no biggie. Very pleased with my purchase.
