I fell in love with these and bought them. I used them a few times, and then my child outgrew them. There are no noticeable stains, but there is some dirt on the soles. I think the undersides are slightly warped. These are colorful sandals with distinctive flower decorations. - Brand: hakka - Size: 16.0 - Design: With flower decorations - Color: Multicolor (blue, pink, white) - Sole Material: Synthetic material Thank you for looking.
