I am not a shoe addict but my feet are picky about what they wear. How many shoes do you have?
Try them all on.
If you only have one pair of shoes, consider yourself lucky that you at least have a pair of shoes.
However, it makes me wonder how varied your life is. Can you really go running, hiking, dancing, fancying and enter posh French restaurants - all with the same pair of shoes? And this is NOT a gender issue!!
Brush, polish and wipe off all shoes and boots.
Check shoe laces and the storage of shoe laces.
Use shoe horns if you have them.
Hang boots with strings and a clothes pin (put paper to protect from pinch-marks).
