The wearer best knows where the shoe pinches.

A person directly affected by a problem understands its discomfort and consequences better than observers do. Firsthand experience gives special authority when describing a private burden or practical difficulty.

The saying advises others not to dismiss, define, or judge someone’s hardship solely from the outside. Those offering help or opinions should listen to the person who bears the effects.

Use it when someone’s account of their own difficulty is being doubted or oversimplified. It can support listening to the affected person, especially when outsiders offer confident judgments without sharing the experience.
