A few points:
1. The chicks that dig boots in a bar likely don't really care if you take them off for sexual exploits.
2. Displaying snake head boots with a sign about them being endangered at the Atlanta zoo will not make those viewing patrons worry about the illegality of the purchase of those boots. Those patrons would be FAR more likely to know the snakes to be endangered by pistols, rifles, shovels, and hoes. That would mean to wear those around might be risking getting one's own foot shot or bludgeoned. Arrest would likely not be the concern.
In Alabama, Arizona, and likely Mississippi wearing those boots would be prone to cause you to prove your citizenship.
