Yes, I have had plantar fasciitis for several years and experience the kind of morning pain you describe. I also have a lot of foot pain during the day if I walk too much.
I use arch supports in my shoes, and I wear "arch sleeves" (little elastic bands that you slide onto your feet to support your arches), and these help some.
