OK. On the left sandel, is that dark mark a part of the shoe that's coming off? FYI...I wouldn't have known that you replied if I hadn't checked back on my own. When you are replying to someone, put your cursor over that comment/question and "reply" will pop up. Click that THEN reply. If you don't, that person won't know you did unless they just happen to check back on their own like I just did. Just thought I'd help you out. :)
