Don't get them too short or your heel and toe will ride on the rolled rib around the outside.  I water, get the mail and paper etc... outside in these too, they have a wrap around sole that keeps the dirt and moisture off the fuzzy.  They aren't too spongy and thick so they are stable walking but they have enough cushion to be soft and comfortable.  My husband doesn't like the sound of them clapping on the kitchen floor but I don't really notice that, they sound like sandals to me.
