From the Keen website: Sandals Sandal Washing Instructions All KEEN water sandals (both leather and polyester webbing upper) are machine washable and have been treated with AEGIS Microbe Sheild, antimicrobial technology that helps prevent odor, staining and deterioration. We've also taken great care to develop leather uppers that will not crack, shrink or stretch when washed. Even KEEN leather Newport sandals are machine washable. Use a small amount of detergent, wash on gentle cycle and air dry. Leather Caring for Leather We've carefully selected leather uppers designed to last. Then again, if you're wearing your KEENS daily, they won't always be scuff and dirt-free. We recommend using a nubuck leather cleaner and conditioner (Nikwax is a brand we like) found at most better footwear dealers and outdoor gear shops. http://www.keenfootwear.com/us/en/custserv_usecare.aspx?section=CaringFor
