I got a pair of shoes at the thrift store this weekend. Shimano shoes for $2 and they seem brand new, never worn. Good deal, eh?

But my question is that I've never worn clip-less shoes...Can I use these for daily use and walk around normally? IE: not do a "penguin walk" at the grocery store? I know I need to buy some pedals, and they come with the cleats I need, but are the shoes/cleats combo "walkable" in a store...I don't intend to wear them all day at work, of course.
