Keep in mind that wool is a material that does not naturally emit an odour upon skin contact and therefore needs not 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 to make your shoes feel softer and more comfortable on 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. Cold water is always better. Avoid other parts of the shoe that may be made of a different material.
