I spend a lot of time in slippers and these are the best!  They are so comfortable with the soft rubber insole and I love that the bottom is NOT rubber so it doesn't mark floors or make dirt marks.  The only drawback is that I have to buy about a pair every year to 18 months because the toes pull out.  I re-sew but they need to double stitch or something.  I have been wearing these for about 18 years and wouldn't wear anything else!  They are expensive but you get what you pay for.  I should sew the toe right when I get them and maybe that would help..lazy me.
