Float is also useful for those of us whose legs are not perfectly straight, causing the heel to move in and out a bit as the crank turns."
That is why I said "often", but I have to wonder... How often is that heel movement just a result of poor fit or bad form?
I thing "often" should be "nearly always". It's not "bad form" it's inherent biomechanics.
Tell me, what is the downside of float? I can't think of any reason not to have it and for most riders it's a benefit. BTW, the Pros all use pedals with float and if there were a disadvantage, they would be the first to complain.
Russell is correct, the float on SPD pedals is symetrical and the OP has (had?) his cleats oriented improperly. Also SPD's have always had 6° of float. Wellgos and their private branded SPD-knockoffs have 4°.
