Fill a bathtub halfway with cold water. Avoid using warm or hot water, because it may damage the sensitive sheepskin.
Submerge your shoes and soak them in the water for 5 to 10 minutes. Squeeze the shoes during this time to push out any trapped dirt.
Rinse each shoe under cold running water. Wring out as much water as you can and allow them to air dry completely out of direct sunlight.
Add 1 tbsp. of baking soda to the inside of each shoe and shake the shoe gently. Allow the baking soda to absorb any remaining odors and moisture overnight. Remove excess baking soda using a hand-held vacuum or small vacuum attachment.
