My daughter used them weekly for swimming lessons one summer so maybe 12-15 hours total. They were kept at the local indoor pool for 30 minutes and I washed them after each class. The colors have almost completely faded from the toe of the shoe (and they're not tight at all - I don't think her toes reach that part, so not from excessive wear). I can't imagine what shape they will be in after using them on the beach! I was hoping to pass this on to your brother or sister, but it doesn't look like it's possible.
