I do all that and use decent spray too, but I go trail running in the mud and wet most days.Socks ?
Shoes?
Try changing socks more frequent even washing won't clear some fungus.
Better fitting shoes .
Don't keep wearing the same footwear.
Soak your feet ,showering doesn’t clean your feet to well.
Let yiur feet breath whenever you can
Other than when the weather`s like this, my feet spend up to an hour every day in wet and muddy trainers, which obs warm up due to running too and make it perfect for it to thrive.
