That's why your feet get hot, Chumly.
That's why mine do, too, if I'm on my feet & on the run all day.
They don't, if say, if I'm sitting at a computer for hours.
Have you ever considered getting shoes made especially for you by a proper shoe maker? (Tasteful shoes
of course!

)
They might cost considerably more, but once you've figured out what best suits your feet, the cost might be well worth it.
