Everything about these slippers is top notch ... good quality, love the rubberish soul (kitchen floor spills don't soak through!).  However, the sawtooth material at the back where your heel goes always ends up getting stuck under rather than behind my heel.  It's uncomfortable and I have to work to get my foot into the slipper in such a way that the material is behind rather than under the foot (as "slip ons", I'd like to be able to just slip them on).

I'm very glad I got these on deal of the day for about $26.  They're regularly much more expensive.  I would recommend you try before you buy to ensure the heel thing works for you.  If they'd fix that design feature, I'd recommend these slippers with no reservations.
