We were having problems finding slippers big enough and wide enough for a relative who is suffering from dementia.  Her feet have swollen and nothing we tried fit her.  Then we found these online and decided to give them a try.  They definitely are pricey, but they fit her well and are really well made.  If the swelling goes down they can be adjusted to fit tighter.  All in all they were a very good buy.  I do wish this company offered a lighter weight version as these may be too hot in summer.
