Abstract: Provided herein is a golf ball that includes a generally spherical surface and an array of dimples formed on the surface. The undimpled portion of the spherical surface is the land area. At least one of the dimples includes a perimeter, a base, and a sidewall connecting the perimeter to the base. The sidewall forms an edge angle with the ball surface.
