How can you tell when someone else wears your shoes?

You can often tell when someone else wears your shoes by noticing if they fit differently or feel less comfortable, as they may have a different foot shape or size. Additionally, signs of wear, like scuff marks or dirt in unexpected places, can indicate someone else's use. If you find them in a different location or see someone else wearing them, that's a clear sign too. Finally, if someone mentions liking your shoes or asks to borrow them, it might suggest they've been trying them on.
