Poor Quality for the Cost !!! Dissatisfied
Disappointed Durability. I love these heels they are very comfortable looks good with just about any color outfit . However, my heart ripped in pieces after 3 months with limited wear they began to lift and fall apart . I’m very dissatisfied with the cost & poor quality slippers I received. I wish I could actually returned it but couldn’t due to the 30 days return policy.

Steve Madden must have
Size: 7.5, Color: Black
You can’t go wrong with any Steve Madden shoe to be honest. These are sexy yet sturdy. Nice thin versatile heel. Strap length is good for any size ankle really

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
