Xue Sheng
All weight is underside
I have been trying to use this in my Xingyiquan, Qigong and even walking and I do feel it is strengthening my knees more than focusing on the Bubbling Well (Yongquan) point which I have always been told to focus on for rooting.

The Mechanics of Three Nails by William CC Chen
Rooting is everything. It is both a base and a foundation. It is one of the most important things in life. A good building must have a strong and firm base. A successful company needs a good foundation. A healthy plant requires a healthy root. The excellent flow of Tai Chi Chuan movements must have a steady, firm root. Without a strong root, the whole body will not be able to relax.
The three active nails, or the points on the foot, form a plane that produces stability under all conditions, and with all physical activities. Whether one is walking, dancing, golfing, or playing tennis, the three active nails create the necessary stability rooting required for the specific activity. Without the ability to firmly root the three active nails, these physical activities could not be performed.
