I was buying replacement SPD cleats yesterday, the store stocked the standard heel-out release cleats but also another type of shimano multi-direction release SPD cleats. I have only ever used standard heel release cleats, anyone know if the multi-release cleates would work well for CX racing to make dismounting easier? I somewhat fear that the multi-release cleates are setup sloppy loose and would be too easy to pull out of the pedal. Are the multi-release just suitable for wanker beginning riders that cannot figure out how to click out and who never output more than 100W or are these cleats suitable for hard riding?
