Feet

[Archie Swivel]

What degree should each of your feet be "fanned" out at address? Reason I ask is that I was reading Redgoat's Fundamentals about the backswing pivot and he speaks of the angle form by the right thigh when the right knee fans out, but with a 90 deg. straight right foot, I cannot perform this action.

If 12 on the clock face is the target line and 6 is between your feet, then angle your forward foot to 11 and your trail foot to 1 - if you must fan out your feet, that is.
Some very successful players stand with their feet perpendicular to the target line whilst others fan out in varying degrees according to personal preference - which is all there is to it really.
