An adjustable golf spike assembly for a golf shoe includes a receptacle fixedly attached to the sole of the golf shoe. The receptacle defines an octagonal recess and an octagonal, externally threaded post disposed within the recess. A cleat includes an oversized gripping portion for providing traction and an attachment portion extending from the gripping portion. The attachment portion has an octagonal outer surface to match and engage with the octagonal recess and an octagonal threaded recess for engaging with the threads of the receptacle. Rotation of the cleat relative to the receptacle longitudinally moves the gripping portion relative to the receptacle. Engagement between the upper portion of the cleat and the receptacle provides for discrete rotational positioning of the cleat relative to the receptacle to position and hold the cleat a desired distance from the receptacle.
