HAFLINGER OLIVIA WOMEN'S WOOL SLIPPERS This slipper from Haflinger is a cute and "wise" take on a playful slipper. These slippers make it easy to snuggle up with a good book on a crisp fall day. This cozy slipper features a boiled wool upper that's naturally lightweight, soft, sturdy, and machine washable. A wool double-felt sole adds cushioning and traction, while the latex arch support keeps you comfortable. The Haflinger philosophy is simple and logical—a healthy foot needs the proper environment and a properly designed walking surface to stay healthy. Haflinger clogs and boiled wool slippers pay particular attention to the needs of your foot—space to expand and contract freely and effectively; breathable, all-natural materials; a footbed and spacious toe box that follow the natural form of the foot; and an impact surface that compliments and fortifies human foot design.
