Purchased last month. Only tried on, never worn. Bought these for my child, but they were a bit small, so they haven't been used, only tried on. (Couldn't return them because I'd already cut the tags) My child usually wears 17.5cm sneakers, but these felt a bit small, and they said going up one size would be just right. My child was happy, saying Pikachu is cute! There's no noticeable dirt or stains. Please understand that these have been stored at home.
