Eagle3, I have to disagree with you. I have posted elsewhere under "Shoes" about the care of white shoes and received some good input.
It seems white leather is "painted" more than tanned, which is when leather is dyed a darker color. I'm no expert, but that's my understanding.
Fieldsy's picture shows flaking of that white finish. I've had it happen to a pair of FJ Contours within 3-4 uses. FJ replaced them. Had the same happen to my son's, but they were so beat up after a few months that I couldn't justify returning them.
I have a brand new pair of DryJoys (white with brown iguana saddle) and I've been using a wet cloth to wipe down the white parts. I plan on doing it each and every time. I keep a bottle of water and some clean rags in the back of my van - precisely for that purpose.
Fieldsy, I guess the question is: would they have flaked like that if you had cleaned them more regularly? I don't know, but it's worth the effort. From my experience, no white shoe polish or cream will restore those shoes to their original state.
