Try and do the foot exercises below. Your feet will love you, and you will also learn to love your feet. This type of activities are also helpful in your battle against plantar fasciitis.
Towel curls
Scrunch your toes, with or without a towel. Just think about the position you leave them in normally. Straight and locked in your shoes like prisoners. To paraphrase Marie Antoinette “Let them scrunch air” or treat them to a scrunch festival on a towel! Give them some manoeuvering room.

Toe splays
Splay your toes: see if you can splay them.

It was a bit of a battle for me to learn how to do this ( as, like you I’ve locked my feet into shoes for the last years, so I alternate the splay with using my fingers to pull them apart ( you can do it en-mass as shown here or individually )

Big Toe stretch
Slowly stretch and pull the toe backward toward your shin. Go as far as is comfortable.
