UPDATE: Today, April 21st, 2011, I bought a pair at CVS for 8 bucks that are better quality than these.

These slippers feel great when you first put them on.  The problem is that they have little structure and break down quickly.  The padding compresses after very little wear.  Even worse, I walk a bit on the side of my right foot and, because the slipper is so mushy, my foot slides off the sole to the right.  Very uncomfortable.
