Rothy's House Slippers. Color is Mountain Gray, with a blue stripe on the heal Knit with a blend of premium merino wool and Rothy’s signature thread. Features a soft sherpa lining and sturdy outsoles. Suitable for both indoor and outdoor wear. Very little wear on the sole, but normal wear and tear on the inserts of the slipper. I've cleaned them extensively with my UGG sheepskin cleaning kits and washed, but couldn't get them clean. You may be able to buy replacement insoles. Women's size 9, runs true to size (unlike other Rothy's styles)
