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.
