Love the comfort of these slippers.  Wore them in my home until I fell off of them, ended up on the floor in my dinning room, with a dislocated foot and shattered ankle.  My belief is that over time the sweater top stretched and failed to support my foot propertly.  Because the sole is so high I either roled my ankle or fell of the sole.  Becareful folks.  It is a year later and I must continue to put ice on my sore ankle.
