Today is of course election day across the United States.
You might as well vote barefoot.
Voting is a fundamental right, and as such, the government is supposed to have a compelling reason for any rule that might restrict your being able to vote. Thus, even a place with a barefoot rule (which normally might only require a rational basis) ought not be off-limits when exercising this special right.
When I pursued my lawsuit against the library, I tried to pull in such a higher level of scrutiny, so that the barefoot rule would be harder for the government to uphold. The reason for this is because the First Amendment is implicated because of the freedom to access printed materials. One reason I lost was because the courts refused to apply that level of higher scrutiny.
But to tell you the truth, I doubt I really needed to tell you the above information. I’ve never heard of anybody turned away from voting simply for being barefooted. I’ve never even heard of anybody being turned away from voting for trying to do so in a library with a barefoot ban.
Those in charge tend to take voting seriously.
If anything, though, you might get a bit of ribbing. Some folks might take your barefootedness as a political statement: either that the current administration has left you barefooted, or, if you vote for the other guy he’ll leave you barefooted.
Instead, just go vote and enjoy yourself, and enjoy your comfort.

Did just vote barefoot and as usual, nobody cared, no weird looks or said anything at all. VA is dixie after all.
Beyond that, it’s pretty much over or at least the beginning of the end. Near or below freezing every night and the pavement just sucks the heat right out of yah. Short walks in daylight are fine, but that’s about it.
Definitely not like gloves, that analogy is bunk. Hands are not in constant contact with freezing pavement.
I voted barefoot, a person handing out propaganda said I was barefoot, I replied with its a symbol of freedom.
