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..
I like how you are counting Dontuz in heels
I have never nor never will wear heels so I stick to the push test. I lead walking up/down stairs with my right foot, I"m right handed too not sure that matters though
