These are Saltwater sandals. (Size 9, equivalent to 16) I received them as hand-me-downs, but they didn't fit, so I'm selling them. I haven't used them since receiving them, and they were worn less than 10 times before being handed down. They were not used for water play. The Velcro is in relatively clean condition and has no adhesion problems. Please check the photos for wear on the soles.
