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

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.
