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.

Beautiful shoe
Size: 7, Color: Smoke Grey
This shoe is fairly narrow, which works fine for my narrow feet. Comfortable. Light. Nice color will match with lots of colors. Fairly comfortable but the skinny part by the toe I see how this would give anyone with a medium side foot blisters. It’s fine on me.

Runs small
Size: 8.5, Color: Sandstorm
This shoe is super cute and comfy. I usually wear an 8 or an 8½. I ordered the 8½, but it was too small, so I had to send it back. I reordered a 9, and it fit perfectly.
