Beat the cold wearing the Muk Luks Winona Slipper Boot. The Safari Slippers are inspired by geometric tribal and animal patterns with hints of exotic metallics shown throughout these styles. Our Winona Slipper has a 100% Acrylic upper, and 100% Polyester Fleece lining. This style has a heel kick for support. Wipe with a damp cloth to clean, no bleach, and lay flat to dry.
