|Can somebody explain to me what pedal float is and what impact it has on road riding.|

|Float referes to the amount of heel movement that your pedel will allow once you are clipped in. For instance, it is usally measured in degress, so if the pedel you are looking at says 5 degress of float you would be able to move you heal from side to side 5 degrees. Some pedels have no float, as the more float you have the more potential for loss of power transfer.
However, a lot of float, like my speedplays, are good for the knees. With float it gives your knees some mobility and can reduce any potential for injury. I have never had knee problems and I think, in part, it is due to my speedplays.

|It's a generalization to say that a lot of float is good for the knees. For many people, it's just the opposite. If my feet are not running directly parallel to the bike (meaning, if my heals are turned even slightly inward or outward), I'll have aching knees. I need a pedal that allows a small amount of float, but also centers my foot on the pedal. In my case, Speedplay Frogs were the worst pedals I ever used, delivering a sensation not unlike standing on ice cubes. My new SPD 959s are much better for me.

|I'll second this..
about a year ago, I read a medical paper by an apparently highly respected Australian sports physiotherapist (sorry can't remember the name) who maintained that for most people, limited or no float offered support for the knee whereas completely free float allowed a lot more potentially damaging movement. He maintained that a large proportion of people's knee problems we actually the result of incorrectly aligned cleats, not the absence of float, and that a lot of float could actually cause problems. This is obviously not applicable to everyone, but...
Anyone else see that?
FWIW, I'm simply reporting from memory & have no view - I use Looks with no problems (apart from extreme frustration at changing cleats every 2 months!)

|You can get pedals with float in one axis (horizontal [Look, Speedplay]) or two axis (horizontal and vertical [Time]). Float can help prevent side to side rolling motion of the knees during pedaling that can cause knee problems.|| |
