A style of the 80s, and 90s, and now, but kind of elusive!
I will ALWAYS be a sucker for anything jewel tone, shiny, rainbow, transparent, sparkly.
Looking at those purple ones reminds me that my older sister had some, maybe when she was 6 or 7...
My mom says: "Don't get em! They'll ruin your feet."
But they're nice to look at.
