Great quality, Highly Impressed!
Size: 12, Color: Light Brown
These are of great quality and surprisingly comfortable. This is my first pair of HEYDUDE. I am really impressed! They are true to size. They fit my wide feet without any issues and they are my new absolute favorites! Super lightweight, extra stylish with the platform lift, and completely worth it. The color matches the photos.

Slip on shoe love
Size: 9, Color: Black/Black, Size: 9, Color: Black/Black
These are a more narrow fit so if you are a wide fit girlie or you don’t like tight fitting shoes you might want to try to size up or try to find something that has a wide version.
But I love them super cute and absolutely great quality..skip on and slip off love it!!! I will be looking into a different color,I got black for work ..but they are comfortable .
Update-after wearing the black suede for a few days I purchased the brown suede as well.... And I can say they do loosen up a little still a a narrow fit but not right feeling.

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 :-(
