Why the bottoms of my feet itch real bad?

Athlete's foot or too much excess skin. Get a pumice stone if it's the latter.

Ring worm ,ground itch ?
If you have walked on the damp ground ,and cats live near by
I would get an antifungal cream
if its from cats ,it can also be contagious
spread in places like the bath or shower

if it gets between the toes ,it can drive you nuts and spreads back and two

But you may just have itchy feet ,,
But if you or a neighbor has cats ,I would not ignore it
It took Terbinafine Hydrochloride to finally stop my agony
It got in my blood once and it took steroids to get rid of it

I was working under a building that was over 100 yrs old ,in water (they had a water leak )and cats were everywhere ,,
The sand under there was like a huge litter box .
that time it almost killed me ,and I spread it to my kids
they got it from the shower
My daughter thought I was being stupid wanting it bleached every day ,,she found out
they needed shots and the cream to beat it too

diabetes, psoriatic arthritis, some kind of neuropathy, vitamin deficiency, lots of reasons. see a doctor get some blood work done if you can.

For me, that's a hives breakout warning

ewww that would be annoying

Try exfoliating them

could be athlete's foot
