Help!....making sense of shoe sizing, gulp

[TrekTheKaty]

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!

Thanks for this molliewog. I need a wide toe box and cycling shoes start narrow! I currently wear mtb shoes.
