If you get a couple hours out of these you are doing good. The glue that holds the inside pad to the bottom of the shoe doesn't hold upto water. This may seem crazy but when these water  shoes get wet the glue stops holding the pad in place. I bought several pairs to use at a water park to walk around in and wear on the rides; they lasted about an hour of light use. We pulled out the pads and used them but pitched them when we left the water park.
