great fit
Size: 4, Color: White
This is my third buy from this brand. They fit great, I have no problem with them at all, and you can't beat the price. You can dress them up with heels and a nice blouse, or wear them casually. I recommend them.

Genuine leather upper and well made
Size: 10, Color: Sunlight
These shoes are well made and I love the way they look. They look great with jeans or dresses. I usually wear a 9 1/2 or 10 depending on the brand. These are a size 10 and fit. Hopefully after a breaking in period the opening at the toes will loosen up. Also, when walking they make a slap slap sound. Again, hoping after they break in that won't be the case. I got a great deal and poof a couple of days later there was a slightly better deal.
I wasn't sure I'd like the color but it's actually really nice. The upper is genuine leather and they are well made.
