Abstract
The present invention is an improved golf shoe which incorporates a spike socket spine frame system that extends throughout the shoe sole for receiving all of the spike receptacles and is embedded in the outsole. The spine frame provides improved shoe performance and spike location and is made of a material that is stiffer than the outsole material. More particularly, the shoe sole is comprised of a spike socket spine having seventeen spike socket locations: three spike sockets in the toe section, six spike sockets in the metatarsal section, four spike sockets in the shank section and four spike sockets in the heel section, for receiving the posts of the golf spikes.
