A good cycling shoe will have a female-specific last to reflect this. In this respect Sidi have come up trumps. The top buckle of the Genius 5s can be repositioned to give the optimum fit, which is particularly suited to narrow feet.
A stiff sole ensures efficient pedalling. An added bonus is that with shoes this shiny, if they do get mucky, a quick scrub in the washing-up bowl will see them back to new.
