Blue kitten heels
Size: 9.5, Color: Blue Leather
These are very pretty shoes with a comfortable heel height. The first time I wore them, they started slipping in the back. The strap that goes around the heel is not adjustable and they ended up flopping as I walked. I ordered my normal size and they fit perfectly so I couldn’t go down a size. Oh well…. Too late to return them.

A very comfortable shoe
Size: 7, Color: Brown Leather
I bought this in a size 7, and it fits beautifully. I normally wear a size 37-38 (European) or a size 8 (US) shoe for walking or jogging. The 3" heels on these shoes are well balanced, making it very comfortable to walk in. The color is a rich dark brown which was just what I wanted. In summary, they fit me good and I'm very glad I bought them.

Disappointing
Size: 7, Color: White Leather, Size: 7, Color: White Leather
Beware: the heel height is not 3 inches! The shoes are comfortable, but the material looks and feels like plastic! I would choose another color.

Elegant, beautiful design
Color: Black
It’s a beautiful bag limited to the size inside but for an elegant dinner engagement it is well worth the money
