I had that…..awful. My MD recommended Birkenstock sandals and they helped a lot .

I’ve had Plantar Fasciitis (PF), for decades. It began when I started daily 5 mile walks for fitness and weight control. I had several years of stabbing pain in my heels when I got up in the morning, and bouts of similar pain all day. My doctor told me to try “Doctor Schols” PF inserts. I tried them, and after several weeks, the pain went completely away.
They are moderately expensive, over 10 bucks a pair, and they wear out regularly. I can tell when they are worn out, because the pain starts up again. I don’t particularly like the design, because they fill only the back half of the shoe, and will move forward during vigorous walking. I have to stop, remove the shoe, and move them back to the proper location. I use them in all of my shoes, even bedroom slipers.
The local HEB pharmacies here in Texas have cheaper store brand inserts that work just as well, as long as I buy only the ones that have the words “Plantar Fasciitis” printed boldly on the label. Ones without that don’t work.
I occasionally find ones there that fill the shoe. These are ideal for me, but they are not always in stock. They have a slight disadvantage in that they must be trimmed with
scissors to fit my shoes.
