Quote - Oh and while you're at it, make toe caps (stocking/sock toes) with their own material zone. When not needed we make these transparent. When needed we can make them have an appropriate cloth material. Instant and perfectly conforming leg coverings of any kind become possible with a simple change of shader material.

I need a specific V value where they connect to the foot, so I can color the toes natural, where the toe cap takes over for the nylon.

If I am understanding this correctly (not so much the shader stuff which I do not) but the toe cap....do you see this as say a floating add-on mesh for the character's toes say like the Upper Brows or the Pubic Hair Prop in V2?
Because if you do that would be wonderful especially if the cap conformed to the toe movements/articulation. God I just got goose bumps thinking of that possibility!  :)
