Comfortable
Size: 8, Color: Natural Snake
These shoes are cute, and go with most everything. They are comfortable and can be work for while without having any issues. I was a bit worried they might rub blisters but have not had that problem with these. The heel and fit of them are perfect. And they are versatile. Worth the price.

Small toe box BUT SOO cute
Size: 8.5, Color: Natural Snake
Very cute but if you have wide toes and typically require a wider toe box you’ll end up with blisters if you walk a lot in them.

Cute but uncomfortable
Size: 6.5, Color: Black Leather
I’m usually a size 6. I got a 6.5, they fit perfect. Super cute, but just from trying them on and walking around my fit we’re already turned red. Still going to wear them to my event but I’m in for one lol

Comfy and perfect heels for the summer!
Love these heels! I’m 5’5”, 120 lbs and size 8.5. They were comfortable from the moment I put them on and I have somewhat wide feet. They are the perfect summer heels!
