For a plus size, tall woman that feet swell these sandals were perfect.They were not tight.They're very comfortable.The straps adjust perfectly and have a little bit of stretch in them.I was able to walk with them with no issue.They actually have great traction on the bottom.And surprisingly very durable.

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.
