This monkey with his AU size 10.5 feet preferred to have his heels on the floor and move the pedals with just his ankles. A bonus was being able to hold both pedals flat on startup just by rolling across one foot.
r22 and r44 is a bit cramped in the footwell for my size 10.5's, maybe this unusual technique alleviates it, but it could also add a bit of unnecessary wear and tear to the mechanism.
