    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

    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.
