Why I pitched barefoot at Demo Day, and tips for being relaxed on stage

If I wasn't balancing damage to spine et. al. with risks to my feet, I'd wear boots suitable for combat, as I did in high school were combat wasn't out of the question. Strong hiking boots, actually, to protect from getting stomped on, and as an implicit message of how I might reply to an assault.
Post-high school, when that would have been clear cut criminal assault, and mobility became more important for avoiding criminal elements, I switched to New Balance 9x9s (high quality running shoes, although I don't run), which I still wear 3+ decades later. Although not around the house.
Anyway, my point is, that as an potential investor, I'd be concerned about your balance of risk and reward; do you feet get dangerously hot that such a risk is reasonable? Severe foot injuries can cascade to death (https://en.wikipedia.org/wiki/Mel_Tappan, albeit I'm sure he was older than you). It would be a factor in my making a decision, even though I've known plenty of people over the years who don't meet my standard of foot protection, including going barefoot, without noticeable harm.

Since hearing that I've tried to follow the rule, still do to this day.
