Heel-and-toe racing is a popular driving technique that involves pressing the brake pedal with the ball of your foot while simultaneously downshifting and rev-matching with the heel and toe of your other foot on the accelerator and brake pedals, respectively. It is a technique commonly used by racers and driving enthusiasts to maintain their speed and momentum through tight corners without sacrificing their balance and control of the vehicle. Synonyms for this racing technique include pivot-foot racing, heel-and-toe downshifting, double-clutching, and rev-matching. All these terms refer to the same driving technique that requires practice and skill to master, but it's a valuable technique that can improve your driving performance on the racetrack and on the road.
