If your feet feel almost glued to the pedals it seems like you must be pushing down significantly even with the foot that's on the upward part of your pedal stroke. So that foot is actually resisting your pedaling motion. Using toe clips (or clipless pedals/shoes) lets you reduce that downward force with the foot that's moving up and become a little more efficient. Yes, you do have to remember to pull your foot out of the clip when stopping but that becomes second nature pretty quickly.
