ABSTRACT:
A golf shoe spike which does not produce so-called spike marks in a putting green due to the use of plastic construction material in which to obviate rupture of the plastic during tightening and untightening preparatory to replacement of a worn spike, the peripheral edge of the spike body is non-circular for improved turning engagement with a wrench having a matching non-circular spike body-receiving compartment and, at each change in direction characteristic of the non-circular spike body edge, a spike is located to provide optimum plastic material since the spike location coincides with a contact site at which the wrench and spike body interengage each other during the tightening and untightening of the spike.
