Runs large
I had to return the shoes. They were too big. Exchanged for a 7. Still a little big, but I'll wear them.

Cute but didn't work out.
While I loved the style when I saw it on the website, it didn't work well with my wardrobe. I also think a different shape (i.e. almond, square toe) suits me better. It was comfortable though.

A great workday shoe
Of course thet are very comfy for a full workday. When just standing the sides do pop out slightly as others have said. It is pretty visible when wearing shorter pants/skirts but easy to forget when wearing longer pants. It doesn’t make them feel too big or fall off my feet, just a little annoying. I personally wish the toe was a little more pointed to elongate the look. The off white leather though is lovely! These are being left under the desk for work wear and not outside just so I don’t get the white material dingy. Overall happy I bought these!

Not what expected
While I like the mules, they are not as pictured. The picture looks like they are slimmer and more feminine - however, they are bulky. While they will be fine to wear with pants, I won't be able to wear them with a skirt as planned because they are too clunky

Hot Feet!
I've worn these shoes just once, and they made my feet really hot, so I wasn't too happy about that. Also, I have plantar fasciitis and after wearing these shoes, it seemed to aggravate my condition. I will try again to see if these same issues re-occur, as I have not experienced these situations with other Vionic shoes that I have purchase and worn with no issues.
