I stretch most of my (left) shoes with a broom handle, right where they are tight at the ball of my foot. My Tahos were easy to stretch, don't know how much a road shoe would stretch. Do you need more room than what you can get by stretching the shoes?

Who does custom bike shoes? that could be a very cool business to be in... (gears are grinding in Knotted's head, always looking for new things to investigate)
