Super fun!
Size: 8.5, Color: Red Pepper
These are so fantastic! The color is amazing! It is a bit on the tomato-red side of the color-wheel. The fit is great. They are comfortable from the 1st step. Easy to walk in.

Footbed very soft and cushiony
Size: 9, Color: Sand
It was so comfortable even though it was a half size too small so i was able to exchange for a larger size. I originally ordered a size 9 and exchanged for a 9.5. I haven’t received the 9.5 yet but I am sure I am going to love them. They are so cute and go with everything.
