I've had these shoes for some years in the red color, have loved them and tried to baby them along, not wearing them too often... as it seems the red version is not replaceable.  Recently took them on a trip to Australia, ( now the heal are not worn down at all, nor any other form of wear and tear)... decided to wear them into the city one day, where a far amount of walking would be required.. but nothing unreasonable.  Upon returning home, I noticed that the rubber sole had split completely across under the sole of one foot...
I still love these shoes, but feel that it should not split across like it has, and there is no way to repair these soles once this happens...
