Keep your feet warm - that is the best advice in winter. Even at home it can be chilly and your feet will need extra protection. Wool felted shoes are the best: they are soft, will get adjusted to your foot shape, they are lightweight, and they are very warm. Some people even stated that their achy feet started feeling better after using wool felted slippers. Wool has unique qualities and its fibers will keep you warm even if you are wet.
Care instructions: wool has self-cleaning properties, so leave your slippers at the freash air once in a while. If they were heavily soiled and got spots, you can hand wash them in warm water with a mild detergent (soap or shampoo). Rinse and let dry on a towel. You can stuff the slippers inside with small towels to keep the shape.
