Eeek! My off white Clarks that I bought just a month ago (direct from the Clarks store) are already having discoloring issues. At first I thought that it was a stain on the back of the heel, but I rubbed lightly on it with my finger and found out that it's the actual stain/color that's rubbing off. It's very slight, but worrisome since I just bought these shoes & have been very careful with them.

So for those of you who are experts at shoe protection:
1. Can I do anything to fix it? Or can Clarks do anything to repair the color? (I've worn them multiple times and cannot find the receipt, so returning them won't be an option.)
2. What would you advise putting on the shoes so that this doesn't worsen or happen again?

I hope they can be fixed. I love these shoes & was happy to get them for a discount. (For some reason they are MUCH cheaper in the brick & mortar Clarks store than on the website or anywhere else.)
