CareWe'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. To treat day to day wear and tear, especially on lighter colour leathers, we recommend using a leather cleaner and conditioner, found at most footwear retailers and/or shoe repair shops.
