Please don't take jackb's advice. I'm sure his heart is in the right place but once you get unconscious about clipping out the advantages of clipless pedals are abundant. Plus if memory serves to do toe clips right you get a little grooved plate for your shoe and pull your strap nice and tight which guarantees a fall or a twisted ankle. Or you get sore toes from pulling up with them.

Did you mention the pedal system you are using? Just curious.
