Nike SB Arioupe. Durable rubber sole. - Brand: Nike - Color: Black - Model: SB - Sole: Rubber sole Size is 22.5cm, but it felt snug on a child who usually wears 20.5cm New Balance shoes. The opening is narrow, making it a bit difficult to put on, and the fit was just right for their foot size. It seems to run small. Although it's listed as new and unused, it has only been tried on indoors. Please refrain from purchasing if you have any concerns. Thank you for looking.
