Although I am only an indoor cyclist, this is a GREAT shoe....comfortable, supportive, and the clips install easily.  Plus they offer a 60-day fit guarantee!  I did have to read many reviews regarding the fit and how to choose my shoe size.  I wear a size 9, but typically go with a 10 in athletic shoes in order to use custom orthotics.  I bought a 42.5 in the IZUMI but am not using orthotics in these shoes.
