Now we know how people walk barefoot on a hardwood floor in front of a camera. And so it goes. We digitize reality and when it fails to resolve into generalization, we adjust reality to fit. It fact, walking is culturally determined. Moccasined American Indian men walked slightly pigeon-toed.
Ballet dancers walk duck-toed.
Heavy men and pregnant women walk differently than thin children, much more focused on their weight shifts. And nothing especially pernicious about focusing on the fine details, either. Folklore has it that Steve Prefontaine, the great distance runner, found an inefficiency in his stride by watching slow-motion videos, corrected it, and improved his times. What is pernicious is losing sight of the fact that digital data is merely representations. Steve Prefontaine didn't learn to run by breaking down the digital data.
