One synonym for "putting oneself in another's shoes" is empathy. This term refers to the ability to understand and share the feelings of another person. It involves being able to step outside of your own perspective and experience the situation as the other person might. Another similar phrase is "seeing things from their perspective." This involves trying to understand how someone else might view a situation based on their own experiences and beliefs. This can help to create greater understanding and empathy between individuals, and can lead to improved communication and relationships overall.
