I bought these based on reviews.  I have foot problems and needed the cushioning from the memory foam because I have tile floors.  I've had these for a week, and the memory foam has lost it's memory.  The heels and balls of the feet portion of the slippers are totally compressed and won't regain the memory foam shape.  Also, they are HOT.  These aren't any better than the cheap pair of scuffs I bought at Walmart.
