Which cleats provide more adjustment freedom? Currently I have MTB shoes and I am surprised how little freedom they provide for left-right adjustment (shift). So I wonder which cleats -- MTB vs road -- provide more adjustment freedom?

Assuming such question can be answered in general (i.e. without ton of exceptions that brand X provide more than Y).

Update there is more than one way to skin the cat -- by adjustment I meant fixing the cleat on the shoe with screws. Not the adjustment when on the bike and small movements which pedal+cleat allow.
All brands and type of cleats offer some left/right floating freedom.

Regular Shimano SPD have a lot of freedom.

Shimano and Looks cleats have different cleats to allow different range of left/right floats.

Shimano SPD-SL Pedal Cleats

Red 0° Float
Blue 2° Float (provided with high-end e.g. Dura Ace SPD-SL pedals)
Yellow 6° Float (provided with most Shimano SPD-SL pedals)


Look Pedal Cleats

Black 0° Float
Grey 4.5° Float
Red 9° Float
