Great
Size: 8, Color: Navy Distressed Denim
These sandals are stylish and comfortable—perfect for everyday wear or vacations. The leather feels soft, and the design looks even better in person. They fit true to size and go well with both dresses and jeans. The only small downside is that they took a couple of days to fully break in, but after that they’re super comfortable. Overall, a great pair of sandals with nice quality and classic style!

Looks good but squeaks
I love these shoes they fit well and are comfortable, however I find myself not reaching for them since they squeak so loudly! I don’t know if they got wet or what but it’s annoying

Beautiful shoe
Size: 7, Color: Greentini Sequin, Size: 7, Color: Greentini Sequin
I ordered size 7. I am 6.5-7 and these were barely long enough. Width was perfect and I would say I have wide “duck” feet.haha. Color is absolutely beautiful. No slip strip is a PLUS. They are very comfortable with all the padding. Sequins seems to be pretty good. I got these at a great price so, I would say great buy for the money.
