Had these for a while and now they sit in their box. I found myself wearing SPD once in a blue moon, and that combined with the negatives of the platform side on the m324s (not great in the wet, no tab to flip them) led me to ditch them in favour of some cheap pinned platforms.

Maybe if my commute distance increases I'll drag out the spd shoes again as well as the m324s, but I find the platforms aren't good enough to warrant keeping them on if you do the majority of commuting in regular shoes.
