These are clear rain boots! I usually wear a 23cm size. I bought a size up, 23.5cm, but the toe area felt tight. So, I think it would be even tighter for someone who usually wears 23.5cm. A 22.5cm size might be best... - Material: Clear plastic - Design: Lace-up - Sole type: Clear sole I only tried them on, but there are some initial scratches. Thank you for looking.
