Heel goes on the brake, toe goes on the throttle. Haha, just kidding.
Left side of foot goes on brake, right side of foot goes on throttle. And then of course there's the left foot which also works well on the brake. Haha, kidding again.
I dunno, I'm just being a jackass. I had a set of Momo's and I hated them. Just a tip... DEFINITELY don't get anything that doesn't actually screw to the original pedal. The clamp crap is just that: Crap.
