Hey Cher....how was racing season?...I figure its about over, thats why you are finding a bit more time these days..lol..
I went through something similar with my feet...they would really hurt like hell in the morning...well, they would hurt all day, but REALLY hurt in the morning...
in a nut shell
I have "semi flat feet"..it seems everything is good until I put weight on them, then the arch flattens right out...stretching the plantar fascia tendon...after working (on my feet) all day, it would be really stretched, and then when I slept at night, it would "tighten" back up...of course it would be aggravated and inflamed also....in the morning , the first weight I put on it was excruciating ...and would take me a good 1/2 hour of hobbling around before i could "kinda" walk...I went to a foot Dr and he is the one who told me what he thought the problem was...I have inserts in my shoes now...it has helped 100%...He wanted to prescribe inserts that are custom made for me..and would last 6months to a year..at a cost of about $300.00..depending on how much I abused them...or he told me i could go to a shoe store and get ones that cost about $50.00 ...they are not quite as good (dont offer the same degree of support)...and they wear out faster.....well...i buy the $50.00 ones every couple months, and I put them in the shoes I wear the most, then put the ones I took out in my next pair of shoes I wear and so on(the shoes I mow the lawn in has the most worn out inserts in them..lol)....now all my shoes ave an insert in it, and even the most worn out ones offer support and my feet have never felt better..
I hope you find some relief...sore feet sucks!...makes anything you do almost impossible :(
