    Researchers at the University of Kansas say that it's easy for people to judge 90 percent of a stranger's personality simply by looking at the person's shoes． "Shoes contain useful information about their wearers．" the authors wrote in the new study published in the Journal of Research in Personality．

Lead researcher Omri Gillath said the judgments were based on the style， cost， color and condition of someone's shoes． In the study， 63 University of Kansas researchers looked at pictures showing 208different 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．

Some of the results were expected： People with higher incomes most commonly wore expensive shoes， and flashier shoes were typically worn by outgoing people． However， some other results are strange enough． For example， "practical and functional" shoes were generally worn by more "pleasant" people， while ankle boots were more connected with "aggressive" personalities． 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 very good care of them， you may suffer from "attachment anxiety"， which means you are likely to spend lots of time worrying about what other people think of your appearance． There was even a political calculation in the mix with more liberal （主张变革的） types wearing "shabbier and less expensive" shoes．

The researchers noted that some people will choose shoe styles to mask their actual personalities， but researchers noted that volunteers didn't fully realize that their footwear choices were showing the deep side of their personalities．
