If you mean the sparkly sneakers, there are a lot of them out there at different price points. The ones she is wearing look to me like P448 or Golden Goose.
@CInnamongirl I agree! They look Dad shoes. They're called that in the UK. Kind of like men's size looking shoes for women. Or as "thick" shoes instead of thin shoes.
Cute. I don't like glitter but I like that style. I just bought the Tristin style (similar to these) from Miz Mooz (here at Q) and they're pricey but certainly not as pricey as the P448 brand.
