The feet should NOT be turned in more than 15 degrees. Constant turning in of the feet more than 15 degrees puts a tremendous amount of strain on the Knees.
The feet are SLIGHTLY turned in to help you find your centre of gravity, and to help you root your stance. The use of this stance in combat is minimal. However, the principals of the stance are applied to combat (maintaining balance, keeping your back straight, even distribution of weight between your legs, etc.)
My feet and knees are no where close to the first picture in KFW's post. If that is how most WC people do their YJKYM; then I guess mine is an anomoly hahaha. My feet are more straight, and my lower half looks and feels more natural. No undue stress on the knees, and I definitely do NOT squeeze the thighs inward. That just seems weird.
Yeah I agree with most of this.
As to 15 degrees...??? I don't know and don't believe it is of much importance as to what the degrees are. My instructors never used a protractor to measure. We tend to pivot the feet inward to the point of having outer edge of the foot pointing straight ahead. The inner edge then projects the sides of a triangle. The knees are bent to the point the distance between them are approx. 2 fists apart.
I am assuming those that use the more intense pigeon toed stance with the knees squeezed in as KPM describes are doing so more as an 'over training' in the beginning stages and they use a positioning much closer to natural in the more advanced stages.
