I've been using my pair of DNA since January, every Saturday. In its rotation with other pairs, I play two rounds in it per week. As for its maintenance, I just give it a dry cloth wipe down each time after a round (If I wanted to keep it in doors as a condition my wife and I agreed upon- to which I do). Once, or a couple of weeks ago, I gave it a damp cloth wipe down... nothing else. It is as good as new as it's looks as clean as it could be- like new!
I also have a couple of Pyramids. One of them is white based. Yes, for some reason, it is more difficult to rub away the dirt/dust stains on its leather cutline than the ChromoSkin leather on the DNA.
Comparing the DNA and the Icon Pyramid shoe design where you see a split are two different constructions.
* Icon Pyramid; the cutline on its leather is exposed.
* DNA; the leather line is folded under. (there are no cut edges exposed on DNA)
This genius construction makes the DNA easier to maintain with a sharp clean look each time. Not that the Icon Pyramids are less... that's just the way they were designed.
