I use platforms only in the dead of winter when I want to wear insulated hunting boots to keep my toes from freezing.

For all other times there's Shimano MO21 mountain shoes. SPD, but I can leave them on at work and I honestly forget that I'm wearing them, they feel like comfy sneakers.

I may think about getting dual-use ones; sometimes I just want to pedal down to the corner store, and having to go inside and get my cleated shoes on is a PITA. But OTOH, I don't like the idea of having to worry about which side of the pedal to use.
