☆ My child wore these indoors for about 5-10 minutes, 1 or 2 times. The fabric is soft and feels nice. ☆ I'm not sure of the size as it's not written, but these were given to me as kids' shoes. (Measured flat, from toe to heel is about 20cm, so they may be made a bit large) ☆ No pets, no smokers. Please refrain from purchasing if you are concerned about the item being stored at home.
