When it comes to the highest quality in cycling SIDI has to be the best. Great fit. Great style. MADE in ITALY! If everyone in cycling made their product like SIDI, we would ride it for 10 years or more and never complain.

NONE I could fine. Price?....... Hint, MADE in ITALY!

On my second pair, and the fit is dead on. Never had a custom pair of shoes, but these have to be the close, Half the price of customs . I have seen customs run $800 or more. I like the 6.6 over the Ergo's, because I was never a fan of the Techno buckle. Same shoe in every way as the Ergo,and a little cheaper in price. SIDI run larger then most brands so I would advise you to try to find a SIDI dealer to try on these shoes. SIDI has strict pricing controls on their shoes, so do not expect to save any $ unless they are on a end of season discount because of the new models. (shopping online won't help on the current models)
Support the LBS on this purchase, there is no reason not to.
