Giro Factor = Road Bliss
I have a mid-narrow width flat foot and find the Factor just about perfect in every fit. Plenty of adjustability, great buckle, great straps, very nice insole with 3 different thinkness arch supports, and very supple leather uppers. The fit is perfect for me with thin cycling socks the venting is very good on 90's and 100's throughout the summer. I wear the white with red version and they look absolutely gorgeous with my white Orbea Orca as well as with my matte black Scott Foil. I ride them with Speedplay pedal, which I find to be flatout the best road pedals on the market, and the cleats work very well on the Easton carbon sole.
A few things to note: the heel cup feels looser then the Shimano, Pearl Izumi, or Mavic shoes I have riden in seasons past. My heels have never slipped, but the other brands make your heel feel locked into the shoe while the Factor feels looser and is comfortable.
Overall, a very nice high end road shoe that fits my feet very well!
