These are very cute, sparkly, and shiny. The fin is made of a strong material and won’t easily bend. The only reason I rated these 4 instead of 5 is that the material is a bit stiff. Between the shiny toe and glittery body, it is all a little bit too rigid. My daughter says they are comfortable, however. Also, you can’t tell very well from the picture, but the right shoe tongue says “MER” and the left says “MAID”, so it spells out mermaid when you are standing with your feet together. Fun detail!
