I bought these 3 years ago for use in public showers and kept them around.  These are quite ugly and really big, every time I look at them, I think clown feet.  Aside from the fact that I think they are the ugliest thing I have ever put on my feet, they are comfortable!  I wear these to the mail box and around the yard all the time since they are easy to slip on and off.  They are strong- 3 years, and they still look like new.  I would never be caught dead wearing these out in public, not even to the beach, but if you are comfortable in them, they are substantial enough to withstand you giving them a beating.  As for comfort, these have a nice soft layer below your foot, so each step is like walking on a cloud.  The shell is sturdy and has a bit of traction to it.  My dog will try and steal them from time to time, but I don't really see any teeth marks on them, so that is another plus.  Three years and they still look like new- I recommend these to anyone looking for a good shower shoe or something for around the yard.  If they weren't so ugly, these would definitely be a 5 star product!
