People are still confusing alignment and float ...

Alignment : cleats are adjustable fore and aft, laterally and radially. Further adjustment can be effected with cleat wedges and spacers.

A competent bike fitter will measure and optimise all those planes to set the most comfortable/efficient attitude for your foot/knees/hips.

Once this position is set float is the angular displacement by which the cleat must be rotated/twisted before disengagement. The cleat will naturally locate your foot on the mid-position - set by the alignment - when pedalling normally. If you're pedalling with your foot constantly straying into the float zone then your cleat alignment is wrong.

The degree of float does not necessarily contribute to the degree of comfort/security you may experience.

Alignment is everything. A bike fit should start from those fixed points.
