I am sorry you are suffering from plantar fasciitis. I had the same problem a few years ago. I KNOW how uncomfortable this can be. I googled ways to find relief. I bought a sock boot that has Velcro on the front of it that can pull your toes toward your ankle this can be adjusted for comfort. It has a another Velcro around the ankle. I found the right comfort and used the sock boot for a few days. It was amazing how this helped me. Night and day amazing. It was not difficult to sleep in,unlike other styles that were hard to wear while sleeping. I had to find the right adjustment so that I did not over extend my toes too much. Please look into it. I don't remember what I paid but It was under $20. Don't let this problem stop you from your success. Let me know how you feel with it. I have not worn mine in years. Also as you loose weight you will have less problems too. Good Luck Robin
