Any imposition that causes injury to another, an action that one should be responsible for, isn't over the line, be it negligent, intentional, or control freaks that don't care about others pain, or well-being.
I've been barefoot as best that I can for several years, now. I pulled my cowboy boots (heels) that I used to live in, out of the closet last week and wore them. I couldn't wait to take them off in a very short time. I was getting crippled and pain in numerous spots in less than an hour. A taller guy, who walks funny. Those shoes are damaging and extreme. They might as well expect women to be chained and hobbled on spikes...actually, now thinking about it, they are on spikes and hobbled.....
The bra requirement is another similar issue. It's prudery causing physical damage and discomfort.
