I had clips and straps on my commuter for a while so I could ride them in my work shoes and still stay connected. I wasn't thrilled with them though because managing the pedals is one more thing to do in traffic. I even used the extra large nylon clips with true MKS platform pedals to help insertion with lugged soles but it was still a pain.

Since then, I have switched to Shimano SPD pedals with platforms on one side. This lets me wear regular shoes in cool weather when I commute in work clothes, and SPD sandals in summer when I ride in bike clothes and change at work. I am much happier with this arrangement.
