Thanks to your replies, I decided to venture out. I contacted a hard core cycling coworker and got the names of the shops that have the largest road shoe selection. I picked one and off I went. Ya, I don't think there is any way I could have ordered online. I think I tried on 6 pairs of shoes!

So despite my hard core online sale loving self, I'm glad I paid more and ended up with shoes that really fit. They are Bontrager race shoes (women's) in a 40. These shoes actually have a wide toe box. Hooray!
