The bit about developing bigger calf muscles from walking on the toe rings true for me. I always ran on the balls of my feet, with my heel almost never hitting the ground - I played a lot of basketball, and you're always moving forward and back, side to side, rarely in a straight line more than a couple dozen yards at most. It's common to say you got "caught flat-footed" if somebody blows by you when playing defense, and we routinely did a drill we called "foot fires," where you step in place on the balls of your feet as fast as possible, keeping balance. I still have to be careful buying pants; I've blown the inseam out of a few pairs of slim-leg jeans below the knee pulling them on too quickly.
