These Haflinger Kris clogs are super easy to use. Just slip them on and you're ready to go, whether you're lounging at home or stepping out. When it comes to maintenance, spot clean the 100% pure wool felt upper with a mild detergent and let it air dry. Avoid machine - washing or using harsh chemicals as it may damage the wool. Make sure to store them in a cool, dry place. Also, be careful when walking on wet surfaces even though the soles are slip - resistant. Enjoy the comfort these clogs bring!
