I used them once for rafting, and the insole (which was supposedly glued in) came off and began sliding around inside the shoe, causing sand and grit to get under the sole and rub against my feet for the duration of the trip.<br /><br />They are also not comfortable.  The sole of the shoe is very thin, so if you're walking on a rocky area, prepare for pain.  I had to wear these as we walked through the woods for a short time, and I could feel every single rock poking against my feet.<br /><br />The mesh also allows sand to get in and rub against your feet.  I don't imagine a lot of people would like that, either.<br /><br />However, they are cheap.  If you need some semi-disposable water shoes you'll only wear once, you might want to consider these.  They went in the dumpster after I got into my dry clothes, because, obviously, I couldn't return shoes that had been worn in the river.
