Everyone’s bodies are all different in unique ways. Also some might have a limp, or crutches, prosthetics, different size feet, wider feet, extremely small feet(while being tall). There would never be enough data. Unless you were there in person measuring.
Well, you have angle of tge thigh and speed and time between strides, giving us stride length assuming their phone is in their pocket, which would be easy to tell. Then you have foot on floor over time and speed, which would give you appoximate shoe length depending on their foot fall. But you could guess that based on axis bounce/force. You could probably guess their weight and gender too.
Samsung health can track some crazy metrics from just the Galaxy watch. I wouldn’t be surprised what else they can accurately estimate. Pic of the data from a recent run.
“Most of the time your phone is in your pocket” he says writing on his phone…
They can probably guess your shoe size and leg length using the accelerometer. Also if you’re right or left handed.
You can’t guess correctly someone’s shoe size and leg length using an accelerometer. There are factors that drastically change the results.
Enough data over time I bet you could. Get a couple drop recordings, arm swing, common heights of beds/desks/chairs, you could find it.
Would it be automated or easy? Hell no. But you can do it. We’ve discovered more with less

Not everyone has the same proportions for every body part. This video is proof. But, since you so confident, make an android app that can measure my leg and shoe size.

You could track when people piss.
