If you have ever judged anyone by what they have on their feet, you were probably right in your original assessment. A University of Kansas study asked people to look at real peoples shoes only and guess characteristics of those people. The participants in the study were 90% right.
The study, which consisted of 63 students who looked at photographs of 208 different pairs of shoes were able to guess the owners person characteristics based on just the style, cost, color and condition of the shoes.
The easiest pieces of information to identify were age, gender and income, but many were also to identify emotional stability and agreeableness.
Expensive shoes belonged to high earners, flashy and colorful footwear belonged to extroverts and shoes that were not new but appeared to be spotless belonged to conscientious types.
Practical and functional shoes generally belong to agreeable people, ankle boots fit with more aggressive personalities and uncomfortable looking shoes were worn by calmer personalities.
