It means that the “you” judges the person even though “you” doesn’t even know why the “i” did the thing she/he did. to put someone in someone else’s shoes indicates that the one person wants the other to know how it feels to be in this situation/ this person. in this situation i’m guessing that someone is attractive and the other is not and the attractive person doesn’t understand the other since they are never in the same situation, but it could also be a metaphor for having bad/ugly charactertraits
