I cant find another shoe that doesn't hurt my feet while sand running AND doesn't allow a ton of sand into the shoe.  For this purpose this shoe is perfect.  However this shoe will not last for very many miles.  I didn't actually calculate miles, it just seemed like they didn't last as long as other shoes.  Eventually the seams at some of the toes split open.  This happened after I run with them in the surf, so it may be because of  the exposure to salt water?  Not sure.  Now that the price of the shoe has gone down to $30, I think they are a great pair of shoes for the price.  Have to wear toe socks w/them otherwise they rub at the heel.  Very flexible and light.
