Kiwi makes a spray-on called, IIRC "Camp Dry". If that is not available, I have used a brand called "Waterguard" that I found at Wal Mart. It has worked on both smooth and rough-out leather without staining, or softenig the molded ones. I can recommend it, but if the Kiwi is available, their leather experience would put it in first-choice place.
