Some people take off their shoes the moment they walk through the door. Others do the exact opposite. They wear shoes from morning until bedtime, whether they are at work, visiting friends or even spending time at home. At first glance, it may seem like a simple personal preference. But psychology suggests there may be more behind this everyday behavior. People who always wear shoes are not necessarily overly formal, stubborn or fashion-conscious. In many cases, their brains may have developed a relationship between footwear and feelings of safety, readiness and emotional comfort. Several well-established psychological theories help explain why.
