I’m told, women start at the shoes and work their way up..

Better think twice before strapping on that ratty old pair of kicks. Get this: After looking at photos of shoes, college students at the University of Kansas could accurately ballpark the owners’ age, gender, income, and even how concerned they were about their relationships, according to an upcoming study in the Journal of Research in Personality.

So the key to someone’s soul is their … sole? Could be. Tom Julian, style expert and author of the Nordstrom Guide to Men’s Style breaks down what your shoe choice says about your personality.

Boots
Attitude: Solid, sturdy, and serious
Boots work for the urbanite or the weekend warrior. Just keep the work boot for when weather mandates, Julian says. And lug boots are a good fit for the guy who mixes work with a rugged weekend, he adds. For a good pair, Men’s Health Assistant Style Editor Kiera Aaron recommends the James Lug Wingtip Boot by Frye.

Attitude: Grounded
This American classic can be trendy if you’re sporting the right pair, Julian says. Your move: Try Cole Haan’s LunarGrand wingtip for the LeBron-worthy Nike Air Technology paired with a dressier look. (www.ColeHaan.com; $250.00)
