I'm always looking for a slipper to wear on our tile floors. My joints need a lot of padding in my shoes. But the real slippers don't seem to have any lining. (And I HATE memory foam!) So when a shoe like this comes along (low back for easy on and off), I prefer to think of it as a comfortable indoor slipper. And I think I found a keeper. Very comfortable, good padding which means lightness to my tile grout. I don't know what they're designed for, but I use what works. And they do their job well.
