I just got an inexpensive one on Amazon. The velcro didn't last long, but then I just put an ace bandage (they make them with velcro) around it to keep it on. This was the one I ordered https://www.amazon.com/dp/B00YZ7CUVQ/ref=cm_sw_r_cp_awdb_imm_21RQEN83605EJ5MSJEDA?_encoding=UTF8&psc=1
It was soft and decently comfortable. Give it a try!
also, my podiatrist was awful. I would recommend getting a second opinion if you can, and also sleeping with a night splint like this one, along with all the constant stretching and croc-wearing.

Sleeping with night splints helped me with the pain for a while when I had a mild case of PF a few years ago. I went with this full-soft boot style kind because none of the other night splint types worked for me:

Also, I would recommend getting some yoga/stretching straps and do your foot/calf/hamstring stretches several times a day, for at least 30 seconds per stretch to help loosen up tension in your ligaments. (That’s what my physical therapist told me to do). And avoid wearing unsupportive shoes, like sneakers with really soft material, flip flops, and ballet flats. Those ruined my feet and the sneakers with too soft of an exterior didn’t work with my custom orthotics and made my PF even worse. It wasn’t till I switched over to some dad-style New Balance shoes that my orthotics started to actually help me.
Also, never go barefoot if you can avoid it. My doctor recommended I wear supportive shoes all the time, even while inside my house.
Night splints did not work for you? I have heard good things about this one: https://www.amazon.com/dp/B00YZ7CUVQ/ref=cm_sw_r_cp_apa_i_akeoDbY1NF8DE
