Keep in mind that wool is a material that does not naturally emit an odor upon skin contact, and therefore needs not to be washed too often. Instead, allow your shoes to aerate in the open every so often, to keep them in their original, enjoyable condition. If you still feel like you need to wash the wool, we recommend using a specially formulated wool detergent that will make your shoes feel softer and more comfortable on the foot. Carefully massage the detergent into the material and remove it with a wet cloth. Let it dry naturally. Remember, do not rub too hard. Coldwater is always better. Be careful to avoid other parts of the shoe that may be made in a different material.
