My daughter in law spends all day in a pair of these and raved about their comfort. I ended up buying a pair for my mother who suffered from rheumatoid arthritis. She loved them and said they were very comfortable. I finally broke down and got myself a pair because, frankly, they just aren't very attractive but, my feet hurt when I'm up and on my feet around the house all day. I only use these as house shoes but, they keep me comfortable and I have not worn my memory foam slippers since getting these. When I have guests and have spend most of the day cleaning and cooking, my back, legs, and feet are usually am aching at the end of day. Not in these! They're not pretty but they keep me pain free.
