Care to elaborate? I'd think as long as you didn't click/release more than a few times per foot, a grocery sack on the outside would be great. It would snap right into the pedal and maybe get a few smallish holes but they'd be within the binding mechanism, so no big deal. I'd rather keep my whole shoe dry.
