If you take care of your sheepskin and wool products properly, they will last a long time. Sheepskin is a living material and features its own natural dirt repellency. Start by airing, shaking and wiping off your shoes – often this goes a long way. Brush with suede brush or wipe gently with a terry towel. Be careful and take it slow. If you need to wash the shoes – use soap and waterproofing intended for the shoe material. Let it dry slowly, preferably fill the shoe with paper and dry at room temperature.
