As found many years ago in most households these traditional boiled wool slippers with their contoured inner sole and flexible latex rubberised outer sole are simply the best (and can be washed as wool). Comfortable original style in grey jacquard check design.
Cleaning: Slippers can be machine washed at 30°C maximum. They must not be put in the tumble-drier, on the heating, or directly in the sun to dry, as this would damage the sole's natural rubber. It's also important not to use fabric softener.
