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.
