'Be in a person's shoes' (or 'put yourself in a person's shoes' or 'in someone else’s place') is an idiom meaning 'to be in, or imagine that you are in, another person’s situation, especially when it is an unpleasant or difficult one. It also means seeing or experiencing something from someone else’s point of view. 'You might feel different if you were in her shoes.' 'Pretend you’re in Tom’s shoes, and then try to figure out why he acts the way he does.'

When I was young. A young American woman told me " if you have money, I will in your shoe". I asked her what does it mean, she replied " I will go to any places you go". In his/her shoe, it looks like that someone is wanting to be with him/her, just like the shoes attached to that person. No matter where he/she goes, the shoes always with him/her.

'In his shoes' is part of an old English proverb; 'before criticizing a man, walk a mile in his shoes'. Meaning: One should not criticize a person without understanding their situation.
