Thank you for viewing. This is a Reef Tourer snorkel shoe. It is 22cm. There are scratches on the shoes, so please refer to the second photo. There are also areas where stones are embedded on the soles. This is shown in the third photo. I am selling these because my child has outgrown them, but they are still in good condition. I washed and stored them, but some sand may come out. They are very light shoes, so my child wore them without any stress.
