I purchased these shoes after doing quite a bit of research on water shoes.  I was heading on a vacation to Bora Bora and needed something to protect me feet from the rocky shore and coral.  These turned out to be better than expected and are a great value for the price.  They are extremely comfortable and breathable and do not rub against my feet.  The elastic band with velcro is very easy to get in and out of.  I've since worn these on local beach walks that required some rock climbing and are even comfortable for short hikes.  I can't speak to how they perform on manmade surfaces (e.g., poolside), but I am very pleased.
