Converse All Star R High Top Navy 26.5cm

Converse All Star R High Top, Navy, 26.5cm. These are new and unused, but because they've been stored for about six months, the rubber part of the sole and the canvas fabric have become whitish where they meet. You can see this if you zoom in on the second photo.
It won't wipe off, so I'm not sure why it's become whitish. I'm looking for someone who is okay with this condition.
