The slippers I bought because of the lining, because my apartment can be very cold in winter. And the slippers also kept what they promised, namely warm feet (and slip resistance). However, one the first fluffy lining is running at the time, of course, quickly / presses it flat, so that even a laundry with washing machine, unfortunately, not much more can be restored or get out. The best you wear it well only one winter or sits down and brushes laboriously the lining into the correct position. Nevertheless, good product!
