I gave a pair of these to my mother and simply put - she loves them.  Often she needs to throw on a pair of shoes and do things like take the dog outside, help with getting groceries into the house, meet a friend on the porch, etc.  The quick comfortable and snug fit grip these to her feet without discomfort.
Her feet also get cold, so she enjoys the faux fur lining and keeps them on in her favorite chair.

An added feature, these slippers (what should really be shoes they are that awesome and well built) have small bear paws imprinted on the soles, so she can hinder evil-doers by making tracks in the snow and they will think that miniature bears are about.

5-5 - when my mother likes something, it has to be good!
