I've recently taken possession of the most beautiful boots in the world (see pic), but by Christ they are murder! I'm trying to wear them at home all day, but am having to do so with the laces laced only halfway up and the side zips down. They are rubbing my heels like buggery! Does anyone have any tips for breaking them in, especially as they are glittery so the dubbin / softening wax is presumably a no go?
