I wear bike shoes with my toe clips (don't really see the need to go clipless when I'm perfectly happy with what I've got!) because I like the extra stiffness, but because I'm primarily commuting, I like a shoe I can walk around it and not look like a dork, so I've got one pair of MTB shoes and I just got the Keen commuter sandals. Love them! You get used to the tighter fit almost immediately and also immediately appreciate how easy it is to slip them into the toe clips.
