DAMP WOOL IS A SOURCE OF HEAT…
Clothes which cannot absorb any or only small amounts of moisture will become wet and damp; they feel cold, and so do we. Wool, on the other hand, has the added advantage, through its own chemical reaction, that it releases heat when it becomes damp. Its ability to give off heat is five times greater than any other textile fibre, and in this manner it acts as a buffer against changes in the surrounding temperature and humidity.
DIRECTLY AGAINST THE SKIN…
The qualities of wool become entirely unique when worn directly next to the human skin, and we recommend you to use your shoes on you bare feet.
Naturally wool has the ability to clean itself, so if you let your shoes have air and rest, they will keep fresh.
You can wash your shoes by hand in warm soap water. Use ordinary washing powder or, if there are spots of fat, washing-up liquid. Leave them in the water 15 minutes. Rub them clean. Rinse out the soap and spin-dry. Put your feet in the moist shoes, and pad them into shape. Washing on wool program is on own risk!
