I haven't tried it in heels (that's my story and I'm sticking to it) but I think I'm more comfortable leading left, and I'm regular.
Well no judgement if you change your story, Donutz...haha! Although I wouldn't advise walking downstairs in heels for this experiment alone.
Yeah so, so far 2 for 2 in stance and stairs.
There might be something to my observation..
