Most people are unable to find shoes for clipless that you can walk comfortably in, and don't look like what an astronaut would wear.. I was fortunate enough to find some I can wear around school all day, or even around town. Shimano somethings, I don't think they make them anymore. Sure they're not running shoes what with the stiff sole (wouldn't want to walk more than 2 miles in them at once), but I'd rather bike than walk around, so the power transfer makes up for it.

If you're actually planning on riding, go clipless
