Huh, I hadn't considered that but that makes a lot of sense. Perhaps that's why I'm seeing the cracking along the entire vamp instead of just where it was stretched. I was thinking of it as more of a conditioner than cleaner but it sounds like I have that backwards. I don't have Lexol or Bick 4, so I'll start by giving it a good dose of AE Leather Lotion. I'll also see if my AE Walnut Premium Polish looks like a good enough match to fill in the light spots. If that doesn't work, I may by the products you suggested. Thank you for chiming in. I'd like to pick his brain on how to do it in the least harsh way. My guess is I was too aggressive with the placement of the (too small) shoe stretcher, the amount of shoe stretch spray I used, and the actual tightness of the stretcher. That, and the aforementioned Reno bath I gave it!
