Because of my diabetes I'm a pretty harsh shoe critic and I just don't like shoes that are made to hurt. I put them on and wear them anytime, anywhere and they are CRAZY comfortable. So much so that I almost forget to take them off when I go to bed. I can't wear a shoe that has to cushion "properly", but this one does. To be honest, I've never taken them in the water. I could buy another pair and take the old ones into the water next summer, but they're great for everyday tennis socks.
