Most people who try clipless pedals do feel that their cycling experience is enhanced. I quit using them for a while because of Plantar Fasciitis. My job involves a lot of short rides with short walks in between the rides. The problem was walking in bike shoes, so I switched from SPD to running shoes and flat platform pedals which was nice and I could wear boots in the cold rain and snow.

Well the foot got better and bikeforums hybrid riders pushed me to get clipped in again. Now all my bikes have clipless pedals. I usually ride in Nashbar SPD sandals. If you're into comfort, you might like.
