Ive been through about 5 pairs of these slippers over the years.  The last pair split on the top and I had to replace.  They last me a year with everyday use. The price is hefty.  They have very supportive arches and thats why I continue to buy them.  They are warm and maintain the comfort and health of my feet.  Im prone to plantar fasciitis.  Best slipper Ive found for the comfort and support.
