Sole

The bottom surface of a golf club head that contacts the ground during the swing, designed with specific angles, widths, and bounce characteristics to optimize performance for different course conditions and swing types. Sole design varies significantly between club types - drivers have minimal sole interaction, while wedges feature complex sole grinds and bounce angles for various shot conditions. Proper sole design helps clubs glide through turf conditions, prevents digging, and promotes clean contact. Understanding sole characteristics helps golfers choose appropriate clubs for different course conditions and shot requirements.
