Despite being a perfectly comfortable and warm slipper, it is poorly made. The lining under the feet is badly glued on. It would bunch up under my toes when I walk, and eventually started sliding out when I took them off. Ultimately, I just pulled the lining out and replaced them with Dr. Shole's inserts. So I had to spend extra money, AND I lost the nice feel of the fuzzy lining. I've bought much cheaper slippers that have lasted way longer. These didn't even last 6 months! And I only wear them for a few hours in the morning and before bed.
