They just aren't as wonderful as I expected for the price.  I expected to feel like I was walking on clouds and these aren't quite there.  Also, I expected more of a "memory foam" experience meaning molding to my foot but that hasn't really happened.  Even so, I like that they're washable.  Mine have been through the washer and dryer multiple (3?) times with no problems so far.  They are comfy...just not over-the-top comfy.  Also, one of the main reasons I got them is because my feet get too hot in fuzzy slippers, especially in the summer.  My feet get hot in these too!
