I agree with some of the previous reviews. They are not of good quality and the plastic on the bottom of the shoes was already coming off. However, in regards to the plastic film that was already coming off; I believe this is a protective film to protect the bottom of the shoes. I'm not sure but it seems to be "purposely" coming off. With the film on, it seems fairly slippery but along the part where it's coming off of the heel, it feels the way the material of a shoe sole should feel. That's just a thought but still not a good quality so returned them. I gave them 2 stars because they are a cute style.
