Broadly speaking, it is what you have (emotion or work or other things that others can evaluate), which you don't think fit, but it's not that bad. Because it's not that bad, others can't say it well. Maybe the essence of this problem is too personal. Put on your shoes yourself. No matter what the reality of this dream is, in the end, you should be the problem rather than others but yourself. This dream is likely to remind you not to make yourself uncomfortable for other people's eyes.
In a narrow sense, shoes generally refer to marriage. Maybe your relationship is in a relatively different situation now, and you don't feel so comfortable. It may be climbing up or marrying down. But others think you're nice.
