Super comfy and cute!
Size: 7, Color: Sky Blue
I wore this for our justice of the peace ceremony yesterday. Went out with a few friends and family afterward and ended up in heels for almost 9hrs straight. I was pretty comfortable the entire time. Toward the last few hours the balls of my feet started to feel a little sore but I feel like that is inevitable when you’re in any heel for that long. My feet are fairly wide across my toes and these had plenty of space which is rare for heels. I feel like they almost always cut into side of my feet. Especially after wearing for a few hours. I worried the lateral being that suede made them look a little cheap-ish, but everyone complimented them. No one agreed about the fabric of even noticed. Just complimented on how cute/sexy they are! I’ve only worn once so far but they held really really for that first wear. Hopefully that’ll be the case for at least a few more wears!

Amazing shoes
Size: 8, Color: Green
Love these shoes! I bought them for a school dance and they were totally comfortable. I love the lace up on them. The only thing I struggled with, is having wider feet, it was a little difficult to fit my foot on the base, but that wasn't the shoes fault at all, they held up nicely and they worked for my needs.

So comfy! True to size! BUY THEM
Size: 9, Color: Red, Size: 9, Color: Red
These heels are my new favorite go to! Normally, I can’t stand my heels after 2 or 3 hours. These heels I can wear for hours on end without any discomfort! No blisters and they didn’t even require me breaking them in. Just super comfortable from the first wear. They’re decently tall so I was surprised how comfortable they are. I love wearing them and I get so many compliments on them. If you’re looking for a pair to wear for long hours, these are seriously the best! They look just like the pictures and fit true to size. I am a size 9 and ordered a 9 and these heels fit perfectly! Just buy them! I plan on purchasing more colors in the future.

Comfy & cute!
Size: 7, Color: Olive Green
I had my doubts that such cute high heeled shoes could be comfy, but these were comfy right out of the box & made it through a wedding with lots of dancing. Comfy, cute & a big hit!
To add: I learned that sizing up by 1/3 size works best for me for all dress shoes, and the 7 worked best for my regular 6.5 size.
