Formal shoes for children. The size is listed as 19.5 cm, but because they run very small, they are suitable for sizes 2 cm to 2.5 cm smaller (around 17 cm). Worn only once for a nursery school graduation ceremony. Size details: At the time, my child was wearing sneakers in sizes 17-17.5 cm, and these shoes fit snugly with a little bit of room.
