Thank you for viewing. Black V-cut design ballet flats with size 38 and non-slip soles. - Color: Black - Design: V-cut - Size: 38 - Sole: Non-slip These shoes have only been tried on. I usually wear 24cm, but I feel they are a little tight, so I think they would be better suited for someone who wears 23cm to 23.5cm. You can also wear them by stepping on the heel.
