Upper material: Boiled wool is used to create these slippers and comes with all of its natural properties, such as insulation, warmth and comfort.
Sole & footbed: The combination of thick felt sole and an integrated, anatomical footbed offers you a cushioned, unmistakably soft appearance. This footbed is non-removable and has been designed to keep you fully functional even after hours of use. Felt outsoles insulate even better against particularly cold floors than variants made of rubber or plastic; they are also gentle on the floor and quiet. For a slip-resistant effect, the thick felt layer on the underside was covered with a layer of latex.
