I’ve seen this image going around, and I feel compelled to point out that it’s only half-right. It’s true that high heels were originally a masculine fashion, but they weren’t originally worn by butchers - nor for any other utilitarian purpose, for that matter.
High heels were worn by men for exactly the same reason they’re worn by women today: to display one’s legs to best effect. Until quite recently, shapely, well-toned calves and thighs were regarded as an absolute prerequisite for male attractiveness. That’s why you see so many paintings of famous men framed to show off their legs - like this one of George Washington displaying his fantastic calves:
… or this one of Louis XIV of France rocking a fabulous pair of red platform heels (check out those thighs!):
… or even this one of Charles I of England showing off his high-heeled riding boots - note, again, the visual emphasis on his well-formed calves:
In summary: were high heels originally worn by men? Yes. Were they worn to keep blood off their feet? No at all - they were worn for the same reason they’re worn today: to look fabulous.
