Heel girly
Size: 8, Color: Burgundy Patent, Size: 8, Color: Burgundy Patent
The bottom is very slippery and you need cushions to go at the bottom of them. You have to be a real heel girly to walk in them, slightly comfortable.

Love color love style. Run extremely small and narrow and that’s saying a lot because I have small narrow feet. Had stuff on bottom of shoe as if it’s been worn
