I have a pair of Sidi Genius 5's. They are not the Mega. I've had them for a few months, they are nice shoes but they make my feet hurt. They are a tad too narrow. Today, I visited a couple of shops here in town and tried several pairs. Shimano - they were nice and felt good enough - I just don't have the heart to wear these with my fully Campagnolo built Seven. Pearl - did not like the way the fit. Northwave - these were a bit of a surprise. Never heard of them, however George Hincapie uses them, they were comfy too. Louis Garneau - these felt pretty good. I don't remember the specific models of the shoes I tried - my bad. I am seriously jonesing for a pair of yellow Mavics. Anyone here waring those? I was told the Sidi Mega's are waaay too wide. I realize feet are like -well, you know - and it is hard to give accurate info... C'mon guys, anyone with some words of wisdom?
