Well, I finally took the plunge. After reading the thread below (and I have been considering it for some time), I switched from my Look Keo pedals to Speedplay Frogs on my road bike and I am very happy with the change. My main reason was to have more walkable shoes, but I hesitated because I didn't want to give up the stiffness of the road shoe sole for a more flexable mountain shoe.

My observations of the diferences are as follows: It didn't take any time at all to get used to them. At first, I couldn't tell if I was clipped in because there is no spring tension and a lot more float than I am used to. It is almost too easy to clip in and out, and walking with the mountain shoes (Sidi Dominators) is so comfortable and no chance of the shoe slipping out from under me when I come to a stop and put my foot down. One difference, you can't unclip by turning your heal inward, as I did with my left foot on the Keos because of a weak left ankle. However, since there is no tension on the Frogs, I had no problem turning my ankle outward to disengage. Since I have never used any other cliples system than Looks, I was used to having my feet locked in tight with very little foat. The Frogs are a plesent surprise and I am very happy I made the switch. Also, now when I look down, I am looking (for now) at a nice new, very CLEAN pair of shoes. As far as the shoes go, my other shoes were Sidi Genuis 5's and the Dominators feel exactly the same. I don't really notice any difference in the stiffness of the sole. There is just a slight sensation that the platform is smaller (which it is), but I think that is also a function of the greater amount of float which feels kind of "glassy".

I'm glad I made the switch (now I have to convince DH to do the same), and I don't care if I am "Fred" for putting mountain pedals on my carbon road frame. You have to do what works!! Hope this thread helps others who are considering various pedals.
