Abstract

An outer sole for a golf shoe includes a plurality of cleats distributed along a forefoot area and a heel area. The cleats are integrated with the outer sole and extend from a surface of the outer sole that faces away from the shoe. The plurality of cleats includes at least a larger sized set of cleats and a smaller sized set of cleats. Such outer sole for a golf shoe gives good traction on the golf course but is also useable as a casual shoe off the golf course.
