I bought these on accident thinking they were a little girl size for my daughter (I don't know why a grown woman would purchase rainbow Hello Kitty slippers).  Amazon told me to just keep them and still refunded my money.  But even essentially for free they are pretty worthless.  They are hard to get on, are slippery on wood floors, and after 2 weeks are falling apart.  I would defintely not buy this design again.
