A male chimpanzee raised in captivity developed a bit of a shoe fetish, masturbating obsessively by rubbing his caretaker's leather boot. High heels are the most fetishized type of shoe. They began with Catherine de Medici, a 16th century Italian who married Henry II of France. The petite Catherine had shoes custom-designed to give her height, starting a high heel rage among the French. Heels still have a way of compelling a gentleman to be gallant.
Submissive men find the extremely spiked heel menacingly arousing, like a lethal feminine weapon.
Dominant men also tend to like high heels, in part because of the way they alter a woman's posture, creating a more dramatic curve of the spine that makes her butt and calves seem rounder, her thighs seem thinner, her breasts stick out, and gives her hips that Monroe sway when she walks. Many men and women are aroused by frailty. Politically incorrect as it may be, this is part of our prehistoric predatory attraction to the weak. Many foot fanciers love sandals, combining the leather shoe with naked toes. The sandal fetish is as old as the Bible.
