Many a people made a killing off of what Hogan and Venturi did with their right shoe, crazy idea right?
What I will say is the "secret in the dirt" notion, which was a byproduct of Hogan's custom spike placement, truly wreaked havoc on my golf swing for years.
While the idea of screwing and planting the right foot into the ground made sense, the hard part was understanding whether the pivot was a lateral motion or vertical one. It was whether the pivot was almost like forcibly twisting the grass or pushing the foot into the ground.
The missing key for me to help make it all come together was coupling a lateral pushing into the ground in the back swing with a vertical pelvic extension on the right side. When done properly, it accomplishes the same notion of having the right knee feel as if it's slightly kicked in, while still allowing for a good pivot to happen in balance.
The other thing this ties to is the vertical stack between the lower body and upper body. The Venturi notion helps basically keep the lower body more target side in the backswing compared to the upper body, which would help a downswing sequence in a more ideal fashion.
But all of this is for a specific set of positions and wrist conditions, it doesn't work for all. In my humble opinion, the idea you are talking about does not jive well with the modern en vogue swing, because the modern swing encourages an unhinging of the torso, a less "torquier" turn, whereas the idea you are talking about is more to create that torque in the trail leg that can "fire" through the ball.
