Thank you for viewing. This is a Reef Tourer snorkel shoe. It is 23cm. There are scratches on the shoes, so please refer to the second photo. There are also areas with stones on the soles. This is shown in the third photo. There is a name written on it in green. I am selling it because my child has outgrown it, but it is still in good condition. I have washed and stored it, but some sand may come out. It is a very light shoe, so my child wore it without any stress.
