I didn't even realize these Inspired by Roxy sets existed until I saw them at the local Walmart. Couldn't resist picking up the set w/ Birkenstocks. So cute! They don't fit the high-heel feet Barbies but do fit the flat feet Fashionistas, and I was able to get them on a curvy doll's feet too. Does anyone know if they've made these in other colors, and if so which dolls/fashions they come with?
