My Mom has worn and loved dozens upon dozens of Daniel Green slippers.  The quality of the product has not changes in 30 or more years.  They are the only slippers which we know about which are available in narrow sizes which makes them even more desirable than any other leather slippers with suede soles.  Regardless, we will only purchase Daniel Green brand since we have been so happy with them for their comfort, quality and color palette for many many years.
