Proper leather shoes

I bought some stretching aid at my cobblers once. it worked really well. I'd try that before getting them to stretch them. because you can use it with your feet to make a better fit and only stretch where it's needed. mechanic stratching at cobblers will often give strange wrinkles/stretch marks(!)
the aid, I bought was a weird foam that you let soak through the leather and the walk in the shoes until dry.

Interesting. Got a link?
