A lot of bad info here IMHO, first of all, it should be called Plantar Fasciosis instead of Fasciitis cos it is rarely inflamed so ice, ibu's etc... is a waste of use.
What you should do is walk barefoot most of the time, if not possible, wear minimalistic shoes with zero drop, wide toe box, no toe spring. (Altra, Vivobarefoot, Leming etc..)
Get rid of the orthotics, only weaken your feet more and more.
Massage lightly with a bal under the foot. Never stretch very tight cos you will only make it worse. Instead do it lightly and stretch your toes cos these can play a big role in PF.
Last but not least look for any triggerpoints in the calf muscle inside the tibia bone, massage your calves with a roller or foam roller.
Plantar fasciosis is the degeneration (deterioration) of the plantar fascia as a result of repetitive stress. This is proven by Dr. Lemont (Temple University) in a study bye the Journal of the American Podiatric Medical Association.
Lemont had looked at tissue samples from 50 patients undergoing heel-spur surgery for chronic plantar fascitis. Like many, Lemont had been taught that plantar fascitis was the result of inflammation of the plantar fascia. "In fact," he wrote, "the suffix '-itis' inherently implies an inflammatory disease."
But that wasn't what he and his colleagues saw under the microscope. Not a single sample showed signs of inflammation. Rather, the tissues appeared to have been damaged from repeated micro-tears and associated cell death. Lemont concluded that this called into question the widespread treatment of plantar fascitis with cortisone shots and anti-inflamatories. If there's no inflammation, such treatments won't work.
