I’ve heard the mule criticized as categorically unsexy — it does, after all, share a name with an animal whose most notable characteristic is its inability to reproduce. (Disappointingly, while both types of mule are hybrids, the shoe actually takes its name from mulleus calceus, footwear worn by magistrates in Ancient Rome that has nothing to do with today’s style). But what mules lack in sex appeal they make up for in cool factor. And what’s more sexy than a woman with the confidence to rock such Man Repellers as midi-heeled slides while sliding into your DMs?
