Fiziks are great. They are kind of a narrow fit on the upper part, but they have a middle sized toe box. The also have a very high built in arch support, so i guess it is not for everybody.
I only tried the r3. The soles are great, full carbon, and very stiff. Great shoes, they are very very well made.
Sidis are the most snug fit pair of shoes i have, they have the smallest toe box, and they generally narrow fit.
Been using a Giro Gauge for my daily commute, and i really like them. The customizable arch support is a great feature. They also have a middle sized toe box. It hugs my foot pretty well. The ratchet system is the best i tried yet, really though, easy to use. The velcros are velcros, not much to say about them. The upper material seems to be very durable, it doesn't really show any sign of wear after six moths of everyday use.
I just ordered a pair of Giro Factor shoes in black, from bike-discount.de, as they are on sale now for 176 euros. They have the EC90 sole, which should be just as stiff as any other high end carbon soled shoes. Factors have two velcros, so you might not like it, but oh well, for this price, its okay for me. I highly recommend you looking into Giro's offerings, they make great shoes, that is for sure.
