P.s I got a custom footbed from Sure foot ($240. Ouch.). Doesn't seem like it's a magical cure and I can't tell if it's helping that much but my doctor told me I need a footbed to avoid lower back pain so I'll keep it in. I was diagnosed with plantar fasciitis.
I found Surefoot was better than stock... but not the best (BurtonAvenger is not a fan of them - he likes to call the "sorefoot")... I personally really like Sole Supports
For plantar fasciitis... look for a foot doctor that has an EPAT machine, that things are completely changed my feet.
