Great quality
Size: 10, Color: Tan
Great quality leather sandals I bought to replace a worn out pair. They are comfortable and not stiff. Hoping the rubber sole lasts a long time. They look nice with jeans, shorts or casual dresses.

Beautiful, well priced, and no discomfort!
Size: 6.5, Color: Taupe, Size: 6.5, Color: Taupe
My daughter wore these for her HS graduation ceremony. So beautiful, well priced, and she never complained about any pain or discomfort. The only downside was that she got an X tanned on her feet! 😆 So put sunscreen on your feet before wearing these.

Love them
Size: 5.5, Color: Red Pepper
I have gotten so many compliments on these shoes! They’re true to size and comfortable. Because of the material feet might sweat easier if hot but they dry quick. Quality is great and the color looks good, it’s more of a orange/red color. I got a 5.5 size
