Ben Hogan's golf shoes were custom made for him in England by the Maxwell Shoe Company. They had twelve spikes instead of the normal eleven.

The extra spike was located under the inside ball of each foot.

There was a reason for that.

Lynn,
Nice addition- In line with Ben Hogan's custom made golf shoes- is a study completed by the Biomechanics lab at The Pennsylvania State University- It was published in the Medicine and Science in Sports and Exercise, Vol. 15, No. 3, pp. 247-255, 1983, where they study ground reaction forces and make several suggestions for shoe design including cleat placement and cleat inclination, among other things.

In addition, quoting from their article:
"The interaction between a golf shoe and the ground is the vital link that allows a golfer to perform the series of body movements during the swing that lead to impact with the ball. Because the movements of the body segments create ground reaction forces at the feet, the study of this interaction provides a unique opportunity to investigate the mechanical conditions existing during the swing."
