100-200mi a year? A530 sounds like the perfect pedal if you absolutely don't wanna just use regular platform pedals with sneakers. If you can't walk in your shoes, you've just gotta get different shoes. I walk around just fine in my MTB shoes with SPD cleats.

Shimano has a line of mountain biking shoes they call "multi-use" and you could play basketball in them if you really had to, all while having an SPD cleat attached to the bottom. Walking on a wood floor would be fine too.

Here's an example:
