Anecdotally, I played football (soccer) as a kid, and multiple coaches taught me that it's better to rest with weight on balls of feet rather than heels for the benefit of being able to quickly move in any direction rather than being planted on the spot. It was just about when standing still or walking slowly, they never tried to adjust how I ran (though maybe if I'd been in a more professional level they would have), but I can imagine that sort of training might well have affected how I walk if I kept playing into adulthood.
