I have owned two pairs of Haflinger slippers in the last 12 years. My first pair lasted those first 11 years, withstood constant wear and washing. Finally the material inside started to separate. What a sturdy pair of slippers. I was a dedicated life long customer, so I decided to buy a new identical pair, only to have the stitching holding the upper material to the sole separate after only 1 year. What a shame! Has anyone else noticed the quality decline from previous years?
