In Hogan's day, all outsoles were flat with no additional traction.The only interaction with the turf came from the spikes. When the metal spikes were placed around the perimeter (usually 11 spikes per shoe) there were some large areas that did not have any traction. Thus, Hogan would have seen some benefit from adding a couple of spikes. There were some comfort issues back in his day though. The spikes under the ball of the foot would often cause discomfort and could lead to blistering on the bottom of the foot.
The current state of golf shoes is very different. Most courses will not allow metal spikes. Plastic cleats are the norm. When the industry went through the change from spikes to cleats there was a change in the overall outsole design theory. Now outsoles are designed with various traction elements that enhance the traction provided by the cleats. FootJoy studied the impact of each cleat position on the overall traction and stability ofthe whole shoe. It was found that certain positions (such as the toe cleat in the "old" configurations) had very little to no impact on the groundforces in the golf swing. We found by moving the toe cleat more medially, traction was enhanced. From this study the current 7 cleat configuration combined with traction elements molded in the outsole was found to provide the optimal traction and stability while enhancing comfort. We went so far as to test shoes without the cleats and found the traction provided by the molded elements in the outsole was nearly as good as those with the cleats in. Bottom line: the traction provided by today's golf shoe technology is better than the state-of-the-art in Mr. Hogan's days. No modifications are needed.
