They don’t fit me anymore

I call them my Peter Pan boots. As you can tell, I’ve used them a lot and that is because they are BEAUTIFUL! I’m thinking I can sell them to someone looking for a vintage and fashionable look. I wore them with shorts jeans leggings EVERYTHING. I’m sad they don’t fit anymore. Very sad. The inside part sticked off but I’m sure some sort of glue will do. Also, they are so comfortable
