The first couple of tries I couldn't get the back part on my foot so I wore them like a slide.  After a week of that I stretched the back manually for about a minute and managed to get them on.  Once on they are comfortable but slippers should not be this difficult to get on.  A wearer should be able to slip into them.  I still need to bend over and work the back to get them on the way they should be worn.  The sale price was ok so I kept them.
