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!

Cute but Extremely Uncomfortable
Size: 6, Color: Blue Leather
The shoes are very pretty, but they are absolutely uncomfortable. I could barely wear them for an hour without my feet hurting. Unfortunately, they look much better than they feel. I really wanted to love them, but they are not comfortable enough to wear for any extended period of time.

Too narrow at the toes, even for narrow feet
Size: 7, Color: Black Leather
Too narrow at the toe. I have narrow feet, but I could feel my toes being squished as soon as I stood up in these.. Bummer.
