I thought all SPD-type pedals had float, and/or it's based on the cleat? I have a variety of Shimano, Wellgo and other house brand compatible pedals and they all have float. I use the same Shimano, Wellgo or house brand cleats with all of them (whichever I happen to have on hand when the old ones wear out). But I have never actually researched this to see if my opinion is correct or how much float they have. All I know is that they have float.

I know that other similar "two bolt" pedal/cleat systems have float: I don't think any Crank Bros pedal/cleats are without float.
