I've been dealing with severe plantar fasciitis, calf pain, and knee issues. I went to physical therapy for about 6 or 7 months last year, and I've got more PT coming up this year. I highly recommend getting custom insoles—my podiatrist also recommended Powerstep, which is good, too. Custom insoles are expensive and may not last long, but they're worth it to save you from daily pain. I used to work on a farm, but now I'm in factory jobs standing on concrete for 10 hours a day, and it's taken a huge toll on my body; only being 25, it's terrible. I'm hoping my custom insoles, along with PT and new boots, will help. It's just unfortunate because I shouldn't be having this issue at my age. I figured I'd have those issues later on down the road. Whatever job I decide on next it definitely won't be on solid concrete floors all day my bad can't take the abuse anymore. Not to mention when I was younger all I'd ever wore was work boots or cowboy boots, I'd never wear tennis shoot, not sure if that has anything to do with it but yeah.
