Love them!

"I love these. Super comfortable. When I ordered based on the pics I thought they were more of an off white but they are most certainly sky blue. So be prepared for the color being more blue than the pics."

— Kristina B. (5/5)

Comfy, stylish shoes

"These heels are super cute. A unique grey, leaning neutral to slightly blue depending on the lighting. I’ve worn them to multiple events without any foot pain. They seem well made. They do run narrow. I normally get a regular width and I did have to get a wide width for these. If you have actual wide feet these will not work for you."
