Cute - change footbed please
Size: 8.5, Color: Dense Smoke
These are so comfy and fit my usually 8.5 foot great. It's the footbed of UGGs that I keep hoping they'll change. It's like our memory foam mattress - cushy and great UNTIL THE HEAT comes! Then it's a no for this hot 65 yo G'ma!

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.

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
