I have always used Looks (Keos) on my road bike with Sidi Genius shoes and I love them, but I am considering Frogs so I can use more walkable shoes. My only reservation is that I don't want to give up the stiff sole of a road shoe. For any of you ladies who have used both the Genius and Dominator shoes, it there much difference in the stiffness? (I guess I want to have my cake and eat it too - stiff sole but walkable.)
