When doing turns either way, your weight should shift to your forward foot (if it's not already there). I don't know if it's strictly good form or not, but one thing that really helps is to shift your lead shoulder slightly in the direction you want to turn. This forces your front foot to pressure the inside edge which initiates the turn.

Yeah, that's me, Tracer Bullet. I've got eight slugs in me. One's lead,
the rest bourbon. The drink packs a wallop, and I pack a revolver. I'm
a private eye.
