Yup.
If I'm not careful, I walk on the balls of my feet and do not swing my arms.
My stride is not even. I take longer steps with my right foot than my left. It has a weird rhythm to it, too.
I have a very heavy tread. If I don't think about keeping my steps light and feminine, I frequently get criticized for "stomping around the house."
If I'm feeling particularly anxious about getting "caught" being autistic in public, I expend enough energy "walking right" that I'm not really paying attention to my surroundings. Stupid thing to do, from an objective standpoint.
