Super comfortable and extremely flattering
Size: 9.5, Color: Black
Love! Love! Love!
Even though they are very flat sandals, the soul has just enough cushion to feel like you’re walking on a cloud. I also love the location of the straps. As someone with bunions, they cover them perfectly and make my feet look attractive while not being completely covered.

Comfortable at first, but didn’t hold up long-term
Size: 8, Color: Tan
The size felt true and the feel was comfortable right out of the box. I liked the softness of the footbed, and the wearability was good for everyday errands and casual outings at first.
Unfortunately, after about six months of regular use, they started falling apart. While the versatility was nice and the thickness felt fine for warm weather, the overall durability just wasn’t there. They’re okay for short-term use, but I wouldn’t expect them to last long.

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
