I find compression helps at least as much as support for my plantar fasciitis.
I'd recommend something like the links below for going barefoot:

I think both companies make a compression band without a cushion, so it won't interference with your insole. (I use 3" elastic sewn in a loop, costs about $1 for a pair.)
Good anti-fatigue mats for anywhere you stand a lot are great as well.
