Walking on clouds…
Size: 6, Color: Blush, Size: 6, Color: Blush
The most comfortable shoes I have ever had. Usually I wear size 6,5 -7. I followed recommendations and order size 6. It was a perfect fit. It was ideal for my problematic wide feet. The shoes are light weight and well made. They look great and feel as cozy as slippers. Absolutely love them and strongly recommend to go size down as I did.

Comfort and fashion collide
Size: 7, Color: Brown Leopard
These platform mules meet the following three criteria points: fashionable, comfortable, and affordable. I wear them all day thanks to the great arch support. In fact, I have three pairs in multiple colors. I normally wear a 7.5 but sized down to 7 after trying a 7 and 8.

Nice looking, quality is iffy 🤷🏻♀️
Size: 7, Color: Black Leather
Love the look of these, nice and comfortable, or so I thought. I wore them for the first time yesterday and they rubbed the top of my foot. I hate that they are lined in a fabric that causes friction. I kept them because I loved the look of them, but, in all honesty I think they are expensive for the quality. My right shoe has scrub marks on the leather :-(

NICE QUALITY
super comfortable and looks just like the picture. I usually wear 8 1/2, but since Hey Dudes don't have 1/2 sizes I purchased an 8, they fit perfect and still feel a little roomy.
