Should the heel be lifted off the ground when releasing the clutch?

The heel should be lifted off the ground when releasing the clutch. The functions of the clutch are: 1. Gradually increasing the driving force of the car to ensure a smooth start; 2. Temporarily separating the engine and transmission for gear shifting; 3. Preventing overload of the transmission system; 4. Reducing torsional vibration impacts from the engine and extending the service life of transmission gears. The working principle of the clutch is: 1. When the inner race is fixed, the outer race can rotate freely in the clockwise direction as the wedges do not lock; 2. When the outer race rotates counterclockwise, the wedges lock, preventing the outer race from rotating. Clutches can be categorized into electromagnetic clutches, magnetic particle clutches, friction clutches, and hydraulic clutches.

Having driven a taxi for fifteen years, I'm most qualified to talk about clutch pedal techniques. When starting off, your heel must lightly touch the floor as a pivot point, while the ball of your foot gradually releases the clutch to control the half-engagement. If your entire foot is suspended, your calf will cramp within half an hour, and you're more likely to stall when it rains. I've seen too many novice drivers operating manual transmissions with floating feet, resulting in clutch tremors like a sieve at red lights. Experienced drivers all know: the left heel must find proper floor support - this allows both precise control of the half-engagement position and relaxed calf muscles. Occasionally lifting the heel a few centimeters in traffic jams is fine, but keeping it suspended the whole time is just asking for trouble.

As a driving instructor, I emphasize the importance of keeping the heel on the floor when operating the clutch with every new batch of students. Beginners often make the mistake of hovering their entire foot above the clutch pedal, thinking it offers more flexibility, but in reality, it only leads to increased leg and foot fatigue. The correct method is to adjust the seat so that the knees are slightly bent, with the left heel grounded as a pivot point, using the ball of the foot to control the clutch pedal's travel. Tests comparing both methods show that with the heel on the floor, the margin of error in semi-engaged clutch control is within 3 millimeters, whereas with the foot suspended, the error exceeds 1 centimeter—this difference becomes even more pronounced during hill starts. Just last week, a student caused a rear-end collision due to clutch slippage from improper foot positioning. Remember, safe driving begins with correct muscle memory.

Last time I accompanied a friend to get his car repaired, I realized there's a trick to driving manual. The mechanic pointed at the worn clutch pedal and said, 'See these marks? The driver probably always hovers their foot over the clutch.' Indeed, many drivers think hovering is less tiring, but in the long run, it not only strains the ankle but also accelerates clutch wear. The mechanic shared a tip: rest your left heel on the cabin floor and pivot the ball of your foot like a compass to control the clutch. After trying it for three days during my commute, the soreness in my left leg during traffic jams disappeared. This method distributes pressure across the foot, avoiding straining the whole leg.
