I absolutely love these Sam Edelman Bay sandals in Atlantic-/Tide-blue. The 9 M fit me perfectly — true to size and very comfortable right out of the box. The leather is soft but sturdy, and the slide design makes it super easy to throw on for errands, brunch, or just relaxing around town. The footbed has enough cushioning that my feet don’t feel tired after a few hours. Overall, great quality and style, and they look more expensive than they really are.

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!
