I suffer from this as well, it comes and goes to this day.
-the frozen water bottle trick previously mentioned works well.
-no running shoes
-boot type shoes with the expensive Green insoles mentioned before really help but can be hard to get used to. I wear those to work. But you can’t wear those all the time.
-vans pros save my feet, I wear them casually and to skate. I have a couple different pairs. I keep the fresh insoles for skating and the really worked in ones for chillin. The worked in ones provide lots of arch support and are basically form fit but hurt heels while skating.
-I’ve also found non skating adidas campus feel good and have lots of support. But also just and authentic non pros are good for some reason. And those have no arch support, I have huge arches I can stand on a golf ball and it doesn’t hurt or impact my arch.
-stress could also Cause it
-also you might have Achilles’ tendon problem. Foam roller those calves, everthingbis connected so a pulled muscle in your foot (plantar) could be caused by another muscle being too tight an the foot gives in.
-I might buy a pair of busenitz because I remember those feeling really good as well.
- be “healthful” if you eat like shit and drink any alcohol, smoke any cigarettes, do ANY drugs you have no excuse and should expect any type of pain to last forever. I found weed actually makes it worst and makes me think about my feet which caused the stress.
-plantar is a nightmare and cost multi millionaire basketball players their career.
-don’t skate or run or walk for a few weeks I’d say just chill til it’s nice in June. I’d wait for it to feel better for 2 months before you skate again. Most of my plantar issue come from landing tricks and tweeting my body so hard to stay on the board. This happens most of the time on grinds and flip tricks for me.
-I also found that if I have sex with a girl in her early 20s the pain goes away for about a week.
Good luck you’ll be fine
