Researchers at the University of Kansas say that people can accurately¹ judge 90 percent of a stranger's personality simply by looking at the person's shoes.

堪萨斯大学的研究人员称，只需看看一个人穿的鞋，就能准确地判断陌生人的90%的性格。

"Shoes convey a thin but useful slice of information about their wearers," the authors wrote in the new study published in the Journal of Research in Personality. "Shoes serve a practical purpose, and also serve as nonverbal（不用语言的） cues with symbolic² messages. People tend to pay attention to the shoes they and others wear."

Medical Daily notes that the number of detailed³ personality traits detected in the study include a person's general age, their gender⁴, income, political affiliation⁵, and other personality traits, including someone's emotional stability.

Lead researcher Omri Gillath said the judgments⁶ were based on the style, cost, color and condition of someone's shoes. In the study, 63 University of Kansas students looked at pictures showing 208 different pairs of shoes worn by the study's participants. Volunteers in the study were photographed in their most commonly worn shoes, and then filled out a personality questionnaire.

So, what do your shoes say about your personality?

Some of the results were expected: People with higher incomes most commonly wore expensive shoes, and flashier footwear was typically worn by extroverts⁷（外向） .

However, some of the more specific results are intriguing⁸. For example, "practical and functional⁹" shoes were generally worn by more "agreeable" people, while ankle boots were more closely aligned¹⁰ with "aggressive" personalities¹¹.

The strangest of all may be that those who wore "uncomfortable looking" shoes tend to have "calm" personalities.

And if you have several pairs of new shoes or take exceptional care of them, you may suffer from "attachment¹² anxiety," spending an inordinate¹³ amount of time worrying about what other people think of your appearance.

There was even a political calculation in the mix with more liberal types wearing "shabbier and less expensive" shoes.

The researchers noted¹⁴ that some people will choose shoe styles to mask their actual personality traits, but researchers noted that volunteers were also likely to be unaware¹⁵ that their footwear choices were revealing deep insights into their personalities.
