These are my second pair of Haflinger slippers.  My last ones lasted close to three years, with very few signs of exterior wear.  I wear them whenever I'm home, and since I work from home, that is a lot of time.  I needed slippers that had good arch support, providing the comfort that I get from my outside shoes, and based on the reviews, I gave these a try.  3 years later I am still very happy with them.  The only reason for a replacement is that the insole lining is wearing out and was starting to bunch up.  I didn't even consider ordering another type of slipper, just placed an order for another pair of these, although in a different color this time.
