The source provides an extensive examination of heel and toe shots in golf, which are defined as mishits resulting from the ball striking the clubface outside of the optimal "sweet spot." It explains that precision in clubface contact is crucial for performance, as off-center hits negatively impact ball flight, distance, and spin. The episode thoroughly details the specific causes and effects of both heel shots (often leading to draws or hooks) and toe shots (resulting in fades or slices), noting how factors like stance, swing path, and grip contribute to each error. Finally, the source offers comprehensive mitigation strategies, including optimizing setup, refining swing mechanics, adjusting equipment, and utilizing modern golf technology to improve contact consistency and lower scores.
