Easy-to-wear, slip-on style black sneakers with elastic straps. - Brand: Nike - Color: Black - Design: Slip-on style - Material: Mesh and synthetic fiber - Features: Elastic straps Thank you for viewing. Color: Black系 (Black-based) There is no size notation, but comparing it to the sizes I have, I think it's probably 17 cm. Easy to put on and take off. There is some wear and tear, but I think it can still be used.
