A new dimple configuration for the surface of a golf ball is characterized by a portion extending above the surface of the ball. Each dimple includes an annular portion having an inner configuration and an outer configuration, and an inner portion having a configuration corresponding with the annular portion inner configuration. Preferably, the annular portion is elevated relative to the ball surface. When a struck ball travels through the air, the elevated portions trip air at the ball surface to improve the flight characteristics of the ball.
